The AS1329A, AS1329B and the AS1329C are synchronous, fixed frequency, very high-efficiency DC-DC boost converters capable of supplying 3.3V at 160mA from a single AA-supply. Compact size and minimum external parts requirements make these devices perfect for modern portable devices.
High-speed switching frequency (1.2MHz) and internally compensated PWM current mode design provide highly-reliable DC-DC conversion, especially when driving white LEDs.
The converters are available as the standard products

AS1329 contain two internal MOSFET switches: one NMOS switch and one PMOS synchronous rectifier.
Anti-ringing control circuitry reduces EMI by damping the inductor in discontinuous mode, and AS1329 exhibit extremely low quiescent current (< 1A) in shutdown.
In shutdown mode the battery AS1329 is connected directly to the output enabling the supply of real-time-clocks.
The AS1329 is available in a 6-pin TSOT-23 package.
