MAX8566ETJ+集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

General Description

The MAX8566 high-efficiency switching regulator delivers up to 10A load current at output voltages from 0.6V to (0.87 x VIN). The IC operates from 2.3V to 3.6V input supplies, making it ideal for point-of-load applications. The total output-voltage set error is less than ±1 over load, line, and temperature.

The MAX8566 operates in pulse-width-modulation (PWM) mode with a 250kHz to 2.4MHz switching frequency range that is programmable by an external resistor. The IC can be synchronized to an external clock in the same frequency range using the SYNC input. The high operating frequency minimizes the size of external components. Using low-RDS(ON) n-channel MOSFETs for both high- and low-side switches maintains high efficiency at both heavy-load and high switching frequencies.
