Features & Applications
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.
The MIC2238 features a selectable mode that allows the user to trade-off lowest noise performance for low power efficiency. Trickle mode operation provides ultra-high efficiency at light loads, while PWM operation provides very low ripple noise performance. To maximize battery life in low-dropout conditions, MIC2238 can operate with a maximum duty cycle of 100%.
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
