Microchip MCP19110-E/MJ, PWM Current Mode Controller, 25 mA, 1.6 MHz, 4.5 → 32 V, 24-Pin QFN

The Microchip MCP19110 and MCP19111 are analogue-based PWM Controllers that integrate an 8-bit PIC Microcontroller. The addition of an MCU allows the operating parameters of the analogue circuitry to be easily customised.

Initial device configuration can be achieved using the Microchip MPLAB® X Integrated Development Environment (IDE). Thereafter PMBus or I²C communications can be used to communicate with the device and modify the configuration.

The MCP19110 and MCP19111 are designed to operate from a single 4.5 V to 32 V supply. Integrated into the analogue circuitry are synchronous drivers, a bootstrap device, an internal linear regulator and non-volatile memory.
