ISL8201M

10A, High Efficiency DC/DC Module

OVERVIEW

The ISL8201M is a 20V, 10A output current, variable output step-down power supply. Included in the 15mmx15mm package is a high performance PWM controller switching at 600kHz, power MOSFETs, an inductor, and all the passive components required for complete DC/DC power solution. The ISL8201M operates over an input voltage range of 1V to 20V and supports an output voltage range of 0.6V to 5V, which is set by a single dividing resistor. This high efficiency power module is capable of delivering 10A (17A peak) output with up to 95% efficiency, needing no heat sinks or airflow to meet power specifications. Only bulk input and output capacitors are needed to finish the design. Utilizing voltage-mode control, the output voltage can be precisely regulated to as low as 0.6V with up to ±1% output voltage regulation. The ISL8201M also features internal compensation, internal soft-start, auto-recovery overcurrent protection, an enable option, and pre-biased output start-up capability.

The ISL8201M is packaged in a thermally enhanced, compact (15mmx15mm) and low profile (3.5mm) overmolded QFN Package Module suitable for automated assembly by standard surface mount equipment. The ISL8201M is RoHS compliant.
