Fairchild unveils 2-in-1 power switch

Fairchild Semiconductor has announced the FSL1x series of FPS Green Mode power switches that the company said delivers high energy efficiency and system reliability. The highly integrated solution is a two-chip-one-package design with an avalanche-rugged 650-800V SenseFET and a current-mode pulse width modulator (PWM) geared to cut component count and system costs for offline SMPS, added the company.

In addition to the green-mode functionality of the PWM controller that helps to meet global energy regulations by minimising standby power consumption, the power switches allow for a longer survival at breakdown mode due to Fairchild's vertical DMOS technology with rugged avalanche characteristics, noted Fairchild. For maximum design flexibility, system productivity and reliability, the FPS family allows for single platform design for various input voltage requirements, so that both domestic and export models can meet all standard passive component requirements.

The FSL1x series features frequency modulation for attenuating electromagnetic interference (EMI) and an internal soft-start circuit that smoothly increases output voltage to help prevent transformer saturation while reducing stress on the secondary diode. Moreover, it touts burst-mode operation to minimise power dissipation in standby mode and has an integrated protection that cuts the need for external components. Protections for the power switch include overload protection (OLP), over-voltage protection (OVP), thermal shutdown (TSD), abnormal over-current protection (AOCP), output short protection (OSP) and auto restart mode.

Samples of the FSL1x series are available upon request with delivery of 8-12 weeks ARO
