Intersil is offering a low noise dc-dc power controller in a thermally enhanced QFN package. Included in the package are the PWM controller, mosfet drivers, power mosfets and inductor along with an optimised compensation circuit.

The intention has been to effectively simplify power supply design by requiring only input and output capacitors and a resistor for the complete system.

The ISL8201M achieves up to 93% efficiency and the QFN package is designed to offer good heat transfer through the PCB. A large copper plate under the package allows the ISL8201M to achieve a power density of approximately 200W/cubic in.

Other features include internal soft-start, auto-recovery overcurrent protection, Enable pin option and pre-biased output start-up capability. The high integration and performance of the ISL8201M is housed in a 15x15x3.5mm QFN package.
