ISL8201M
10A, High Efficiency DC/DC Module
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.
