MAX8643A regulator equivalent, 2mhz step-down regulator.
fixed-frequency PWM mode operation with a switching frequency range of 500kHz to 2MHz set by an external resistor. High-frequency operation allows for an all-ceramic capa.
Total output error is less than ±1% over load, line, and temperature. The MAX8643A features fixed-frequency PWM mode op.
The MAX8643A high-efficiency switching regulator delivers up to 3A load current at output voltages from 0.6V to (0.9 x VIN).The IC operates from 2.35V to 3.6V, making it ideal for on-board point-of-load and postregulation applications. Total output e.
