New Yorker Electronics has updated its line of power ICs with the new Vishay Siliconix SiC462 4.5V to 60V Synchronous microBUCK Regulator. The device is a synchronous buck regulator with integrated high-side and low-side power MOSFETs. The device is a high-efficiency buck regulator with a power state able to supply a continuous current of 6A at a switching frequency of up to 1MHz.

This regulator provides an adjustable output voltage down to 0.8V from 4.5V to 60V input rail to support a variety of applications, including consumer electronics, computing, telecom and industrial. The device has a programmable switching frequency of 100kHz to 2MHz. The device's control scheme is based on voltage mode constant-on time, so it provides an ultra-fast transient response with minimum output capacitance and tight ripple regulation at a very light load.

The device is stable with any capacitor and its power saving scheme significantly boosts light load efficiency by permitting diode emulation mode and frequency fold-back as the load decreases. It also allows loop stability, regardless of the type of output capacitor used, including low-ESR ceramic capacitors. Therefore, no external ESR network is needed for loop stability.
