Product details
MCP19124 PWM controller with 8-bit MCU
The Microchip MCP19124 is an analogue-based PWM controller with an integrated 8-bit PIC® microcontroller. The combination analogue and digital solutions within a single device results in a product that maximizes the strengths of each technology to create a configurable, high-performance and more cost-effective power conversion solution. The MCP19124 contains two independent and configurable outer control loops which take advantage of a faster, inner current loop for peak current-mode control with fast transient response. This unique architecture allows smooth and monotonic switching between constant-voltage and constant-current operation which can be accomplished dynamically during operation.
Smooth, dynamic transitions between CC and CV operating modes
Dynamically adjustable output current and output voltage
Wide operating voltage range: 4.5-42V
Analog peak-current mode PWM control
Fixed-frequency or quasi-resonant operation, adjustable 31 kHz to 2 MHz
Supports Boost, SEPIC, Flyback, and Cuk topologies
Minimal external component count
Integrated 8-Bit PIC® MCU allows significant configurability
I2C communication interface
9 GPIO lines
Custom algorithm support
