ISL8205M

DATASHEET ISL8205M 5A Single Channel High Efficiency DC/DC Step-Down Power Module FN8755 Rev 4.00 October 25, 2016 The ISL8205M power module is a single channel synchronous step-down complete power supply, capable of delivering up to 5A of continuous current. Operating from a single 2.6V to 5.5V input power rail and integrating controller, power inductor and MOSFETs, the ISL8205M only requires a few external components to operate and is optimized for space constrained and portable battery operated applications. Based on current mode PWM control scheme, the ISL8205M provides a fast transient response and excellent loop stability as well as a very low duty cycle with an adjustable output voltage as low as 0.6V and better than 1.6% accuracy over line and load conditions. Operation frequency is selectable through an external resistor, with a 1.8MHz default setting, or may be synchronized with an external clock signal up to 3.5MHz. The ISL8205M also implements a selectable PFM mode to im...
