... DETAILED DESCRIPTION 4.1 Device Overview The MCP16301 is a high input voltage step-down regulator, capable of supplying 600 regulated output voltage from 2.0V to 15V. Internally, the trimmed 500 kHz oscillator provides a fixed frequency, while the Peak Current Mode Control architecture varies the duty cycle for output voltage regulation. An internal floating driver is used to turn the high side integrated N-Channel MOSFET on and off ...

... PULSE-WIDTH MODULATION (PWM) The internal oscillator periodically starts the switching period, which in MCP16301’s case occurs every 2 µs or 500 kHz. With the integrated switch turned on, the inductor current ramps up until the sum of the current sense and slope compensation ramp exceeds the inte- grated error amplifier output ...
