.. 4 2 V, 1 - 2 C e l l s , M i c r o p o w e r, D C - D C B o o s t C o n v e r t e r 1 General Description The AS1343 boost converter contains a 1.4A internal switch in a tiny TDFN-10 3x3mm package. The device operates from a 0.9V to 3.6V supply, and can boost voltages up to 42V output. The output voltage can easily be adjusted by an external resistor divider. The AS1343 uses a unique control scheme providing the highest efficiency over a wide range of load conditions. An internal 1.4A MOSFET reduces external ponent count, and a fixed high switching frequency (1MHz) allows for tiny surface-mount ponents. The AS1343 also Features power-OK...
