IS6607A is a high power density, high frequency, fully integrated synchronous step-down converter. With a 3mm x 4mm 21 PIN QFN package. It can support a continuous output current of up to 20A. It has a very high working efficiency in the output load current range, and it has a good load adjustment rate and linear adjustment rate in the wide input voltage range.

IS6607A adopt the internal compensation mode, and use the unique TCOT^TMControl mode to provide fast transient responses and simplified loop compensation networks. The switching frequency can be selected between 600 kHz, 800 kHz and 1 MHz. The soft start time can be set by the external capacitor. The PGOOD signal is provided to indicate the working state of the chip.
