6A, 2MHz Step-Down
Regulator with Integrated Switches
General Description
The MAX8646 high-efficiency switching
regulator delivers up to 6A 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 error is less than ±1% over load, line, and temperature ranges.
The MAX8646 features 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 capacitor design.
The high operating frequency also allows for small-size external components.
