PWM Current Mode Controllers
PWM Current Mode Controllers are DC-DC regulators designed to control the output voltage by varying the maximum inductor current cycle to produce a controlled voltage independent of switching current and input voltage. These controllers are comprised of various types with trimmer oscillators for duty cycle controls, high gain error amplifiers, comparators, and temperature references ideal for power MOSFET drive.
What do PWM current mode controllers do?
These controllers are ideal for regulating offline DC-DC conversion applications and offer cheaper solutions with a range of exterior components. Furthermore, they come in surface mount and through-hole mounting types with different package options. In addition, they feature various pins for ground and power output stages.
Where are PWM Current Mode Controllers used?
Current-mode PWM control devices are ideal in environments where the following parameters are required.
- When supply output is high current or very-high voltage.
- The fastest dynamic response at a particular frequency.
- Input-voltage variations are controlled.
- Minimized components’ costs and numbers.
Furthermore, they are also designed to be used for:
- DC Converters
- Isolated Power Supplies
- Distributed Power Supplies

MCP19118-E/MJ, Microchip
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 Microchips 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.
