Product details

MCP19118/19119 PWM Controllers with 8-Bit PIC MCU

MCP19118/19119 devices from Microchip are highly integrated, mixed signal, analogue pulse-width modulation (PWM) current mode controllers with an integrated PIC® microcontroller core for synchronous DC/DC step-down applications.

The integrated PIC® microcontroller mid-range core allows complete customisation of the device operating parameters, start-up and shutdown profiles, protection levels and fault handling procedures. After initial configuration using Microchip’s MPLAB® X Integrated Development Environment (IDE) software, the PMBus or I2C can be used by a host PC to communicate with or modify the operation of the device.

Features

Wide operating voltage range – 4.5-40V
Analogue Peak-Current Mode Pulse-Width Modulation (PWM) Control
Integrated 8-Bit PIC® Microcontroller
Significant Configurability – Adjustable Analogue Compensation, Switching Frequency, UVLO, OVLO, Start-up Behaviour, MOSFET Dead-Time, Configurable GPIO Pins, Internal Compensation Network, I2C Communication Interface
Integrated Synchronous High and Low-Side MOSFET Drivers
Integrated Current Sense
Integrated 10 bit A/D Converter
Minimal External Components Needed
Custom Algorithm Support
