Programming Specifications:
The MCP19122 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. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution. With integrated linear regulator, driver, timer, temperature sensor, and feedback network capabilities, this creates a very compact, versatile power conversion solution.
The output is adjustable on the fly, using the integrated programmable gain amplifier in the feedback path and the integrated adjustable reference voltage. In addition, the internal compensation network can also be adjusted, preserving phase margin and transient response over a wide (0.3V to 16V) output range (without external components, that range can be shifted with resistive dividers).
- Wide Operating Voltage Range: 4.5-40V
- Wide Output Voltage Range: 0.3-16V
- Supports synchronous buck, or similar high/low side switch topologies
- Operates from 100kHz to 1.6MHz, adjustable during operation
- 4kw flash memory
- 256B RAM
- Significant Configurability: Adjustable Analog Compensation, Switching Frequency, UVLO, OVLO, Start-up Behavior, MOSFET Deadtime, Configurable GPIO Pins, Internal Compensation Network, I2C Communication Interface, and fault behavior
- Integrated Synchronous High- and Low-Side MOSFET Drivers
- Integrated High-side Current Sense
- Integrated 10 bit A/D Converter
- Can provide or synchronize to an external clock
- Can provide or synchronize to an external reference
- 50uA quiescent current draw in sleep mode
- Integrated POR and BOR functions
- Three internal timers and a capture compare module
- Integrated I2C interface, capable of PMBusTM support
- Minimal External Components Needed
- Custom Algorithm Support
