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 NiMH 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 combined 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 component 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 250mV. Other features include internal digital soft-start, independent channel enable for power sequencing, overcurrent protection, and thermal shutdown. The ISL78236 is offered in a 24 Ld 4mmx4mm QFN package with 1mm maximum height. The complete converter occupies less than 1. 5cm2 area. The ISL78236 is AEC - Q100 qualified and is rated for the automotive temperature range (-40°C to +105°C).
