GENERAL DESCRIPTION
The XRP7720 is a quad output universal customizable PMIC comprised of a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) controller and 5V LDO. A wide 4.75V to 5.5V and 5.5V to 18V input voltage dual range allows for single supply operation from standard power rails. It is pin compatible to the popular XRP7724 and provides full flexibility during the development phase while offering a cost effective option for high volume production units.
With integrated FET gate drivers, it can
operate from 105kHz to 1.23MHz with
independent
channel-to-channel
programmable operating frequency, the
XRP7720 reduces overall component count
and solution footprint while optimizing
conversion efficiencies. A selectable digital
Pulse Frequency Mode (DPFM) and low
operating current result in better than 80%
efficiency down to 10mA load provides support
for portable and Energy Star compliant
applications. Each XRP7720 output channel is
individually programmable down to a
minimum 0.6V with a resolution of 2.5mV, and
configurable for precise soft start and soft stop
sequencing, including delay and ramp control.
During development, the XRP7720ILB-DEV is configured using PowerArchitectTM 5.1 (PA 5.1) through an I2C interface, allowing for short development of the power system and short time to market for the entire system. Once development is completed and volume production i...
