Microchip Technologies' new sophisticated power supply pulse width modulation (PWM) controller consists of a high-speed comparator with a high-performance error amplifier and a PWM latch to perform the analog power-supply PWM function. The MCP1630, when used with a microcontroller, supports the development of high-speed, intelligent power-system controllers. The microcontroller can control the output voltage (or current), switching frequency, maximum duty cycle and other features making the system more intelligent and adaptable. The device supports all SMPS topologies and is best suited for applications requiring medium-to-high levels of intelligence and operating at frequencies exceeding 200 kHz. It has a low operating current of 2,8 mA (typical), and supports peak-current mode operation up to 1 MHz. It has a precise peak-current limit of ±5%. The MCP1630 comes in 8-pin MSOP, and operates over -40 to +125°C.
