AS1343 42V, 1-2 Cells, Micropower, DC-DC Boost Converter Data Sheet 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. 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 applications. The device is available in a low-profile TDFN-10 3x3mm package. 2 Key Features 5.5V to 42V Adjustable Output Voltage 0.9V to 3.6V Supply Voltage Range High Output Currents - 30mA 12V VOUT, from 1.5V VCC - 40mA 24V VOUT, from 2.5V VCC Efficiency Up to 85% Switching Frequency 1MHz Output Disconnect Function Power-OK Output Quiescent Current 22µA Shutdown Current 0.1µA TDFN-10 3x3mm Package 3 Applications The device is ideal for OLED display power supply, LCD bias generators, mobile/cordless phones, palmtop computers, PDAs and organizers, handy terminals, driving LEDs or any other portable, battery-powered device.
