2 independent digitally controlled channel outputs
Voltage mode PWM control with 625 ps resolution
Remote voltage sensing on both channels
Programmable compensation filters
Voltage feedforward option
Flexible start-up sequencing and tracking
Switching frequency: 50 kHz to 625 kHz
Frequency synchronization
Independent channel protections: OVP and OCP
2 independent OTP circuits
Programmable fault protection sequence
Volt-second balance and dual-phase current balance for interleaved configurations
On-board EEPROM
PMBus-compliant
Graphical user interface (GUI) for ease of programming
Available in a 40-lead, 6 mm × 6 mm LFCSP

APPLICATIONS
AC-to-DC power supplies
Isolated dc-to-dc power supplies
Intermediate rail power supplies
Nonisolated dc-to-dc power converter
