The ISL8203M offers an independent Power-Good (PG) signal for each channel. When shut down, the ISL8203M discharges the output capacitor. Other features include internal digital soft-start, enable for power sequence, overcurrent protection and over-temperature protection.
The ISL8203M integrates a PWM controller, synchronous switching MOSFETs, inductors and passive components to maximize efficiency and minimize external component count. The ISL8203M is available in a thermally-enhanced, compact QFN package.

Industry-Leading 10A and 15A Fully Encapsulated PMBus Power Modules
The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks – even under heavy load conditions.
