General Description

The AS1322A and the AS1322B are synchronous, fixed frequency, very high-efficiency DC-DC boost converters capable of supplying 3.3V at 150mA 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 DCDC conversion, especially when driving white LEDs.

Key Features

95% Efficiency Single-Cell Operation Delivers 160mA @ 3.3V (from Single AA Cell) Delivers 220mA @ 5.0V (from Two AA Cells) Delivers 570mA @ 3.3V (from Two AA Cells) Low Start-Up Voltage: 0.85V High-Speed Fixed-Frequency: 1.2MHz Internal PMOS Synchronous Rectifier Automatic Powersave Operation (AS1322A) Continuous Switching at Light Loads (AS1322B) Anti-Ringing Control Minimizes EMI Logic Controlled Shutdown (< 1µA) Output Range: 2.5 to 5.0V 6-pin TSOT-23 Package 3.
