The MIC2238-J4YML TR is dual output, High-efficiency synchronous step-down DC/DC converter. The MIC2238 is ideally suited for portable systems which demand high power conversion efficiencies while offered in a very small package. The MIC2238 offers an ultra-low quiescent current in light load mode assuring minimum current draw from battery powered applications in standby modes.
Features:
High Efficiency: Up to 95%
Ultra-low quiescent current: Only 28 µA
Ultra-low shutdown current less than 1 µA
2.5 MHz PWM operation
High output current capability per channel: 800mA
No Schottky Diodes Required
Stable with 2.2 µH inductor, 2.2 µF ceramic capacitor
Adjustable output voltage down to 0.8 V
Built-in soft-start circuitry
Current limit protection
Automatic switching into light load mode operation
FPWM pin allows low noise all-PWM mode operation
Power good output with internal 5 µA current source allows sequencing with programmable delay time
Small Thermally Enhanced 3 mm × 3 mm MLF ® package
Applications:
Cellular phones
PDAs
Digital cameras
MP3 players
