XRP7724ILB-F - Exar Corporation Function Overview

The XRP7724ILB-F is a 4-channel digital pulse width modulated (DPWM) step down Buck Controller 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 XRP7724 reduces overall component count and solution footprint and optimizes conversion efficiencies. A selectable digital pulse frequency mode (DPFM) capable of better than 80% efficiency at light current load and low operating current allow for portable and Energy Star compliant applications. Each XRP7724 output channel is individually programmable as low as 0.6V with a resolution as fine as 2.5mV and configurable for precise soft start and soft stop sequencing, including delay and ramp control. Built-in independent output over voltage, over temperature, over-current and under voltage lockout protections insure safe operation under abnormal operating conditions.
