Infineon Technologies IR3513MTRPBF

Description
The IR3513 Control IC provides comprehensive control for a scalable number of phases. It incorporates an internal gate driver, current sense/sharing, and PWM. This allows the IR3513 to function as a stand-alone single-phase regulator or interface with additional Phase ICs to create a power solution with any number of phases. This approach requires only 1 IC per phase for 1 to X phase deployment.

Features
0.8V reference supports 0.8V to 5.1V output voltage with /-0.5% system set point accuracy
Dynamic margin function provides ±5% reference offset
1 (stand-alone) to X phase operation with additional Phase ICs
Programmable 250 KHz to 9 Mhz daisy-chain digital phase timing provides a per phase switching frequency of 250 KHz to 1.5 MHz with no external components
Differential remote sense amplifier with 100kohm input impedance
IC bias linear regulator control with programmable output voltage and UVLO
Programmable converter current limit during soft-start, hiccup with delay during normal operation
Over voltage protection communicated to Phase ICs
System over voltage signal protects against failures such as a shorted high side MOSFET
Detection and protection of open remote sense lines
Open control loop protection
7V/2A gate drivers (4A GATEL sink current)
Integrated boot-strap synchronous PFET
Small thermally enhanced 32L 5 x 5mm MLPQ package
