Three to four switching buck (step-down) controllers
each with internal FET drivers
Output voltages programmable from 0.9V to 5.1V
Up to 6 (re)configurable GPIO pins
Fully programmable via I2C interface
Independent Digital Pulse Width Modulator (DPWM)
channels with five coefficient PID control
High Integration: elimination of external circuits and
components required for compensation, parameter
adjustment and interface
Programmable DPWM frequency range (300 kHz
to 1.5 MHz) enables efficiency and component size
optimization
Complete power monitoring and reporting
Independently controlled start-up delay and ramp for
each regulator
Independently controlled soft-stop delay and ramp for
each regulator with a programmable stop voltage
Over-temperature protection (OTP) and Under Voltage
Lockout(UVLO);per-channelover-currentprotection
(OCP) and over-voltage protection (OVP)
Built-in LDO (configurable to 3.3V or 5V) with over-
current protection
