The MCP19123 offers excellent regulation accuracy, in a variable output analog PWM controller with an integrated microcontroller for supervisory and management functions. It is a mid-voltage (4.5-40V) analog-based synchronous buck PWM controller with an integrated 8-bit PIC® Microcontroller. This unique product combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution.

Wide Operating Voltage Range: 4.5-40V
Wide Output Voltage Range: 0.3-16V
Analog Emulated Average-Current Mode Pulse-Width Modulation (PWM) Control
Supports synchronous buck, or similar high/low side switch topologies
Operates from 100kHz to 1.6MHz, adjustable during operation
Integrated 8-Bit PIC® Microcontroller
