AS1322A

300mA Buck-Boost Synchronous DC/DC Converters; 95% Efficiency\nSingle-Cell Operation\nDelivers 150mA @ 3.3V (from Single AA Cell)\nDelivers 500mA @ 3.3V (from Two AA Cells)\nLow Start-Up Voltage: 0.85V\nHigh-Speed Fixed-Frequency: 1.2MHz\nInternal PMOS Synchronous Rectifier\nAutomatic Powersave Operation (AS1322A)\nContinuous Switching at Light Loads (AS1322B)\nAnti-Ringing Control Minimizes EMI\nLogic Controlled Shutdown (< 1μA)\nOutput Range: 2.5 to 5.0V\n6-pin TSOT-23 PackageApplications\nThe AS1322 is ideal for low-power applications where ultra-small size is critical as in medical diagnostic equip ment, hand-held instruments, pagers, digital cameras, remote wireless transmitters, MP3 players, LCD bias supplies, cordless phones, GPS receivers, and PC cards.;

General Description\nThe 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.\nHigh-speed switching frequency (1.2MHz) and internally compensated PWM current mode design provide highly reliable DC-DC conversion, especially when driving white LEDs.Key
