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.
