Microchip | MIC2251-1YD5-TR

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
