Features & Applications
This device is designed for use with inductor values from 4.7 µH to 22 µH, and is stable with ceramic capacitors from 1 µF to 22 µF and it incorporates a pseudo-random dithering function to reduce EMI levels up to 10dB enabled by the DITH pin. It is optimized for noise-sensitive hand held battery powered applications.
Features:
- Over 80% efficient for a 300:1 load range
- 2.5 V to 5.5 V input voltage range
- Output voltage adjustable to 32 V
- 52 µA (typ) quiescent current
- Constant peak current control reduces output ripple
- EMI reduction circuitry
- Stable with small ceramic capacitors
- <1 µA shutdown current
- UVLO and thermal shutdown
- 8-pin 2mm x 2mm leadless MLF package (MIC2251)
- 5-pin Thin SOT-23 package (MIC2251-1 and -2)
- -40°C to +125°C junction temperature range
Applications:
- LCD/OLED display bias supply
- CCD bias supply
- Mobile phones, PDAs, media players, GPS, PND
- Haptic displays
- Local 5V, 15V, 24V rail
