AS1343 - DC-DC Boost Converter

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.

Key Features

  • power-OK circuitry which monitors the output voltage. Additionally the AS1343 features a low quiescent supply current and a shutdown mode to save power. During shutdown an output disconnect switch separates the input from the output. The AS1343 is ideal for LCD or OLED panels with low current requirements and can also be used in a wide range of other.

Datasheet AS1343 www.DataSheet4U.com 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 component count, and a fixed high switching frequency (1MHz) allows for tiny surface-mount components. The AS1343 also features power-OK circuitry which monitors the output voltage.
