Description

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

Model

Light Load Switching

AS1329A

Powersave Operation (medium loads)

AS1329B

Powersave Operation (light loads)

AS1329C

Continuous Switching


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.
