DATASHEET ISL8201M FN6657 Rev 3.00 10A, High Efficiency DC/DC Module October 28, 2014 The ISL8201M is a 20V, 10A output current, variable output Features step-down power supply. Included in the 15mmx15mm Complete Switch Mode Power Supply package is a high performance PWM controller switching at 600kHz, power MOSFETs, an inductor, and all the passive Bias Voltage Range from +4.5 to +14.4V components required for complete DC/DC power solution. - Wide Input Voltage Range from 1V up to 20V (see The ISL8201M operates over an input voltage range of 1V to Input Voltage Considerations on page 11) 20V and supports an output voltage range of 0.6V to 5V, 10A DC Output Current, 17A Peak Output Current which is set by a single dividing resistor. This high efficiency Adjustable +0.6V to +5V Output Range power module is capable of delivering 10A (17A peak) output with up to 95% efficiency, needing no heat sinks or airflow to Up to 95% Efficiency meet power specifications. Only bulk input and output Simple Voltage Mode Control capacitors are needed to finish the design. Utilizing Fixed 600kHz Switching Frequency voltage-mode control, the output voltage can be precisely regulated to as low as 0.6V with up to 1% output voltage Fast Transient Response regulation. The ISL8201M also features internal Enable Function Option compensation, internal soft-start, auto-recovery overcurrent protection, an enable option, and pre-biased output start-up Pre-biased Output Start-up Capability capability. Internal Soft-Start The ISL8201M is packaged in a thermally enhanced, compact Overcurrent Protection by Low-Side MOSFET r DS(ON) (15mmx15mm) and low profile (3.5mm) overmolded QFN Sensing (Non-Latching, Auto-Recovery) Package Module suitable for automated assembly by Small Footprint, Low Profile Surface Mount QFN Package standard surface mount equipment. The ISL8201M is RoHS (15mmx15mmx3.5mm) compliant.
