High-Efficiency Synchronous Buck Regulator Evaluation Board
The ISL9107EVAL1Z provides a complete evaluation kit for the ISL9107 1.6MHz switching frequency, low quiescent current, high-efficiency integrated step-down...
ISL9107 and ISL9108 are 1. 6MHz synchronous step-down regulators with integrated power switches capable of delivering 1. 5A output current, which is ideal for powering low-voltage microprocessors in compact devices such as PDAs and cellular phones. These devices are optimized for generating low output voltages down to 0. 8V. The supply voltage range is from 2. 7V to 5. 5V allowing for the use of a single Li+ cell, three NiMH cells or a regulated 5V input. 1. 6MHz pulse-width modulation (PWM) switching frequency allows using small external components. They have flexible operation mode selection of forced PWM mode and Skip (Low IQ) mode with typical 17µA quiescent current for highest light load efficiency to maximize battery life. The ISL9107 and ISL9108 integrate a pair of low ON-resistance P-Channel and N-Channel MOSFETs to maximize efficiency and minimize external component count. The ISL9107 offers a typical 215ms Power-Good (PG) timer when powered up. The timer output can be reset by RSI. When shutdown, ISL9107 and ISL9108 discharge the output capacitor. Other features include internal digital soft-start, enable for power sequence, overcurrent protection, and thermal shutdown. The ISL9107 and ISL9108 are offered in 8 Ld 2mmx3mm DFN package with 0. 9mm typical height. The complete converter can occupy less than 1cm2 area.
