XRP7725

Quad Channel Digital Pulse Width Modulated (DPWM) Buck Controller

Description

The XRP7725 is a quad channel Digital Pulse Width Modulated (DPWM) step-down (buck) controller. A wide 4.75V to 5.5V and 5.5V to 25V input voltage dual range allows for single supply operation from standard power rails.

With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.23MHz independent channel to channel programmable constant operating frequency, the XRP7725 reduces overall component count and solution footprint and optimizes 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 XRP7725 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.

The XRP7725 operation is fully controlled via an SMBus-compliant I2C interface allowing for advanced local and/or remote reconfiguration, full performance monitoring and reporting as well as fault handling.

Built-in independent output overvoltage, over temperature, overcurrent and undervoltage lockout protections insure safe operation under abnormal operating conditions.

The XRP7725 is offered in a RoHS compliant, “green”/halogen free 44-pin TQFN package.
