The AS1344 boost converter contains a 1.4A internal switch in a tiny 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 AS1344 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 AS1344 also features power-OK circuitry which monitors the output voltage.
AS1344 also offers a Softstart function which limits the current during startup. The current during startup can be easely adjusted with the value of RV. For RV = 0, there is no softstart.
Additionally the AS1344 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 AS1344 is ideal for LCD or OLED panels with low current requirements and can also be used in a wide range of other applications.
AS1344 is available in a low-profile TDFN-10 3x3mm package.
