com PM1299 POWER MANAGEMENT UNIT (PMU) COMPLEX 3-CHANNEL POWER MANAGEMENT UNIT (PMU) DESCRIPTION The PM1299 is a complex 3-channel power management unit (PMU).
The PM1299 include one independent input for very low dropout regulator (LDO) and 1A high efficiency of the Sync Buck DC-DC, and a very unique PWM controller which can be boost, buck or both boost/buck, it can drive MOSFET or cheap cost of BJT.
The PM1299 can be flexible for design, for example, two buck and one LDO, or one buck, one boost and one LDO, more than this, PM1299 can apply to be constant current driver of LED backlight.
FEATURES  1A Sync Buck DC-DC  One Flexible PWM Controller  one channel 500mA LDO  Very small package in QFN16 (3x3) for PCB saving APPLICATION  5V supply for ADSL MODEMs  5V Supply for STB, IPTV  Digital Photo Frame, MID, E-book…etc.
 Others single cell Li-on Battery and 5V supply electric products ORDERING INFORMATION The PM1299 is available in QFN16 (3x3) packages.
Package Type Part Number QFN16(3x3) PM1299Q16R Q16 PM1299Q16VR Note V: Halogen free Package R: Tape & Reel AiT provides all RoHS products Suffix “ V “ means Halogen free Package TYPICAL APPLICATION REV1.
