FN8624 Rev.1.00 Mar. 14, 2017
The ISL78236 is a dual output, 3A/3A, integrated FET buck regulator for point-of-load power applications. The supply voltage range is from 2.8V to 6V, allowing for the use of a single Li+ cell, three Ni MH cells, or a regulated 3V/5V bus input. It is optimized for regulating output voltages down to 1.2V. Each channel provides an output current up to 3A, which can be bined to form a single 6A output in current sharing mode. The two channels operate 180° out of phase to reduce input RMS current and EMI.
The ISL78236 integrates a pair of low ON-resistance P-channel and N-channel internal MOSFETs to maximize efficiency and minimize external ponent count. It can operate up to 100% duty cycle to maximize operating life as battery voltage drops out. When supplying 3A on each channel, the 100% duty cycle operation limits the dropout voltage to less than 250m V....
