PWM ICs offer enhanced features

Suited for high-performance synchronous buck dc/dc converters, the IR3622MPbF and IR3622AMPbF dual-phase PWM-control ICs can be configured to support a single output in current-share mode, capable of delivering 80 A, or to support two independent outputs. The independent channels run 180 out of phase and reduce the required input capacitance.

The IR3622MPbF targets 12-V single-input applications while the IR3622AMPbF can support 5- and 12-V applications. Key protection features include selectable hiccup or latched current limit, prebias startup, thermal-shutdown protection, and under- and over-voltage protection. Available in 32-lead MLPQ packages, the parts also feature a programmable switching frequency up to 600 kHz as well as two independently programmable soft-start functions.
