## Description

The IR3621MTR from Infineon is a versatile dual synchronous buck controller and driver IC designed for high-performance power supply applications. It operates in a 2-Phase mode, enabling either two independent output voltages or a single output for high current applications through current sharing.

Key features include a programmable switching frequency up to 500kHz per phase, allowing for flexible system tuning and simplified filter design through synchronization. The controller also incorporates independent soft-start functions for controlled output voltage sequencing and pre-bias protection to prevent damage during startup. Protection features such as selectable hiccup or latched current limit and under-voltage lock-out provide system security.

This component is suitable for applications like embedded networking, telecom systems, distributed point-of-load power architectures, 2-Phase power supplies, graphics cards, and DDR memory applications. It is supplied in a Tape & Reel package, with a standard quantity of 6000 units.

The IR3621MTR operates with a Vcc supply voltage range of -0.5V to 16V and a VcH supply voltage range of -0.5V to 25V. It features a precision reference voltage of 0.8V and a power good output.
