DESCRIPTION

LTC3290

High Voltage Boost Charge Pump

Demonstration circuit 2585A contains two circuits fea-

turing the LTC

3290. The top LTC3290 circuit operates

as a high voltage boost by using the power from two

input supplies to create a higher output voltage. The bot-

tom LTC3290 circuit operates as a VIN tracking supply by

using the power from an auxiliary supply input (V

AUX

) and

regulating a voltage above the VIN supply input. The wide

VIN/VAUX range allows two voltages to be used together

to efficiently create a third voltage, boost from a single

supply to boost, or regulate above a variable input voltage

like a battery.

The high efficiency boost circuit has three selectable out-

puts, 15V, 24V, or 42V. If a different output is desired then

the top resistor, R2, and/or the bottom resistor, R6, can

be changed to provide a different output voltage. Refer

to the LTC3290 data sheet and demo board schematic

for more information on how to set the output voltage

for the LTC3290.

All registered trademarks and trademarks are the property of their respective owners.

PERFORMANCE SUMMARY

The VIN tracking circuit also has three selectable outputs,

IN2

+ 5V, V

IN2

+ 10V, and V

IN2

+ 15V. If a different output

voltage is desired, then R9 and/or R13 can be changed

to set a different output. Refer to the LTC3290 data sheet

for more information on how to set the output voltage in

VIN tracking mode.

The LTC3290 can use two separate supplies or a single

supply connected to both inputs for either circuit. This

can be useful to boost or track a battery voltage with a

regulated output.

The LTC3290 data sheet gives a complete description of

the device, operation and application information. The data

sheet must be read in conjunction with this demomanual.

Design files for this circuit board are available.

Specifications are at TA= 25°C

ASSEMBLY TEST PROCEDURE

Refer to Figure1 for the proper measurement equipment

setup and jumper settings and follow the procedure below.

NOTE: When measuring the input or output voltage

ripple, care must be taken to avoid a long ground

lead on the oscilloscope probe. Measure the input

or output voltage ripple by touching the probe tip

directly across the VIN or VOUT and GND terminals.

See Figure2 for proper scope probe technique.

HIGH EFFICIENCY BOOST CIRCUIT

1. Make sure the jumper settings are as follows:

JP1: VOUT1 is on the 15V position.

JP2: EN1 is on the HI position.

2. Set PS1 and PS2 to 1V and then turn on. If AM1 and

AM2 < 10mA then set both PS1 and PS2 to 10V.

NOTE:Make sure that the sum of VIN1 and VAUX1

≤55V.

3. Set LD1 to 5mA and observe the output voltage, IIN,

IAUX and the output ripple on an oscilloscope.

4. Increase the load slowly up to 50mA and observe the

output voltage, IIN, IAUX, and the output ripple on an

oscilloscope.

5. If it is desired to observe PGOOD1, set PS3 to 3.3V as

shown in Figure1 and observe PGOOD1 with a DVM,

VM4 in Figure1.

6. If a different output voltage or input voltage is desired,

disable the LTC3290 by moving JP2 to the LO posi-

tion and then turn off LD1. Then move JP1 to the

desired VOUT1 selection or replace R2 and/or R6 to

obtain the desired output voltage. Then re-enable the

LTC3290 by returning JP2 to the HI position.

NOTE:If R2 and/or R6 are to be replaced, turn off

PS1 and PS2 to prevent damage due to soldering a

hotcircuit.

7. Adjust PS1 and PS2 to the desired voltages and turn

on and set LD1 to the desired load.

8. When done, turn off LD1, PS1, PS2 and PS3.

VIN TRACKING BOOST CIRCUIT

9. Make sure the jumper settings are as follows:

JP3: EN2 is on the HI position.

JP4: VOUT2 is on the VIN2 +5V position.

10. Set PS4 and PS5 to 1V and then turn on. If AM4 and

AM5 < 10mA then set both PS4 and PS5 to 10V.

NOTE:Make sure that the sum of VIN2 and VAUX2 ≤ 55V.

11. Set LD2 to 5mA and observe the output voltage, IIN,

IAUX, and the output ripple on an oscilloscope.

12. Increase the load slowly up to 50mA and observe the

output voltage, IIN, IAUX, and the output ripple on an

oscilloscope.

NOTE: When the LTC3290 is disabled, VOUT is high

impedance and can be 0V. If an electronic load is

placed from V

OUT2

to V

IN2

, V

OUT2

can have a negative

potential with respect to VIN2. Care must be used with

loads that are high impedance when disabled when

connecting a load between VOUT2 and VIN2.

13. If it is desired to observe PGOOD2, set PS6 to 3.3V as

shown in Figure1 and observe PGOOD2 with a DVM,

VM9 in Figure1.

14. Slowly decrease PS4 to 5V and observe the out-

put voltage, IIN, IAUX, and the output ripple on

anoscilloscope.

15. Slowly increase PS4 to 24V and observe the out-

put voltage, IIN, IAUX, and the output ripple on

anoscilloscope.

16. To observe VOUT2 with respect to VIN2, place a DVM

from VOUT2 to TP1, VIN2. A differential oscilloscope

or isolated scope probe can be used to view VOUT2

with respect to VIN2.

NOTE: Do not short TP1 to GND.

17. If a different output voltage or input voltage is desired,

disable the LTC3290 by moving JP3 to the LO posi-

tion and then turn off LD2. Then move JP4 to the

desired VOUT selection or replace R9 and/or R13.

Then re-enable the LTC3290 by returning JP2 to the

HI position.

NOTE: If R9 and/or R13 are to be replaced, turn off

PS4 and PS5 to prevent damage due to soldering a

hot circuit.

18. Adjust PS4 and PS5 to the desired voltages and turn

on and set LD2 to the desired load.

19. When done, turn off LD2, PS4, PS5 and PS6.

BOOST CHARGE PUMP WITH VOUT REGULATION

The LTC3290 can be set up as a high voltage boost charge

pump by utilizing two supply inputs to boost to a higher

regulated voltage. To operate in this mode the VSET pin

is tied to GND and VOUT is set by a voltage divider from

VOUT to GND. The output is regulated to a 1V reference

compared to the voltage sensed on the FB pin.

The VOUT output voltage is given by:

VOUT =1V • R2

R1 +1

⎛

⎝

⎜

⎞

⎠

⎟

VIN TRACKING MODE BOOST CHARGE PUMP

The LTC3290 can also be set to regulate a fixed voltage

above an input voltage. With this circuit a resistor on the

FB pin is used to set up a current using a 1V reference. A

second resistor is connected between the VOUT and VSET

pins to set a voltage above the VIN supply.

The VOUT voltage in this configuration is given by:

VOUT =VIN +1V • R2

⎛

⎝

⎜⎞

⎠

⎟

AVAILABLE OUTPUT CURRENT

The available output current can be limited by the effective

open-loop resistance (ROL). The ROL is affected by the

oscillator frequency, value of the flying cap, nonoverlap

time, internal switch resistance, and ESR of the external

capacitors. The typical ROL is 65Ω and can increase with

temperature.

The available output current is given by:

IOUT =VIN +VAUX
