Intersil has introduced the ISL8203M, a dual 3A/single 6A step-down DC-DC converter module with a footprint of just 9.0mm x 6.5mm, the world’s smallest for this type of device.
Offering efficiency up to 95% and excellent thermal characteristics, the module provides power-system designers with a high-performance, easy-to-use solution for their low-power, low-voltage applications.
The ISL8203M is a complete power system which simplifies power-supply design for FPGAs, ASICs, microprocessors, microcontrollers and DSPs. It is housed in an encapsulated module which includes a PWM controller, synchronous switching MOSFETs, inductors and passive components, producing a power supply which supports an input-voltage range of 2.85V to 6V. The ISL8203M’s adjustable output voltage of 0.8V to 5V enables designers to use just one device to build either a single 6A or a dual-output 3A power supply.
The ISL8203M power module offers best-in-class thermal resistance of 15°C/W junction-to-ambient when mounted on the device’s evaluation board in free air. It can also supply a 6A output at an ambient temperature of 85°C without the need for heat-sinks or a fan.
The module draws on Intersil’s patented technology and advanced packaging techniques to deliver high power density, allowing it to operate at full load over a wide temperature range. The module also provides over-temperature, over-current and under-voltage lock-out protections, adding to its robustness and reliability.
The ISL8203M power module is available in a 9mm x 6.5mm x 1.83mm QFN package.
