New power IC is capable of delivering up to 75W output power
New Yorker Electronics
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.
