MCP19114/5: Digitally Enhanced Power Analog Synchronous Low Side PWM Controllers

The MCP19114 and MCP19115 hybrid digital-analog control solutions offer the speed and responsiveness expected of a high performance analog control loop; the flexibility expected of a digital MCU; operate across wide operating voltage ranges; support conventional 5V, 12V, and 24V rails; and meet automotive load dump requirements. The MCP19114/5 analog-based controllers with digital interface, offer cost efficient adjustability in a high performance power conversion solution. The two devices are functionally equivalent with the MCP19115 offering more GPIOs.
