QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 903A

STEP-UP /STEP-DOWN DC-DC CHARGE PUMP CONVERTER

LTC3240-3.3 and LTC3240-2.5

DESCRIPTION

Demonstration circuit 903A is a step-up/step-down

charge pump dc-dc converter. It comes with two assem-

bly versions, DC903A-A and DC903A-B featuring the

LTC3240-3.3 and LTC3240-2.5 respectively, each in a

tiny 2mmx2mm DFN package.

The DC903A-A and DC903A-B generate a fixed regulated

output of 3.3V and 2.5V respectively over a wide input

voltage range from 1.8V to 5.5V. The output current can

reach up to

150mA

when the input voltage is above 2.5V

in DC903A-A. The maximum output current of DC903A-

B is designed at 60mA over the full input range.

The DC903A optimizes the output efficiency by operating

in the LDO step-down mode during most of the battery

life time when the input is higher than the output volt-

age. When the battery voltage gets low enough it auto-

matically switches into charge-pump doubling mode to

maximize the battery usage.

Additionally, DC903A features Automatic Burst Mode

operation at light load to achieve low supply current

(65µA, no load). Also, the built-in soft-start limits in-

rush current at turn-on, and short-circuit current

limit/thermal protection help the part survive a continu-

ous short-circuit. All these features make the circuit ide-

ally suited for efficient DC-DC conversion in space-

constrained applications such as battery-powered hand-

held electronics.
