Smallest dual 3A/single 6A step-down power module
The module’s 9.0 x 6.5 x 1.83 mm footprint combined with 95% efficiency provides power system designers with a high performance, complete power system in an encapsulated module that includes a PWM controller, synchronous switching MOSFETs, inductors and passive components to build a power supply supporting an input voltage range of 2.85V to 6V. With an adjustable output voltage between 0.8V and 5V, designers are able to use one device to build a single 6A or dual output 3A power supply.
Designed to maximise efficiency, the ISL8203M power module offers best-in-class 15° C/W thermal performance and delivers 6A at 85° C without the need for heat sinks or a fan. The ISL8203M delivers high power density and claims the best thermal performance available, allowing the ISL8203M to operate at full load over a wide temperature range. The power module also provides over-temperature, over-current and under-voltage lockout protection.
Internal digital soft-start is achieved in 1.5msec; there is external synchronisation up to 4MHz. The device is priced at $5.97 (1000). The ISL8203MEVAL2Z evaluation can be purchased for $67.
