The MIC23250-S4YMT-TR from Micrel Inc. is a 4MHz dual synchronous buck regulator designed for high efficiency, particularly at light loads with its HyperLight Load™ mode. This regulator is suitable for applications requiring fast transient response and low output ripple, such as processor core voltage supplies.
Key electrical specifications include an input voltage range of 2.7V to 5.5V, with each of the dual outputs capable of delivering up to 400mA. It boasts a peak efficiency of up to 94% and maintains 85% efficiency at a 1mA load. The device features a low quiescent current of 33µA with both outputs enabled and operates at a constant switching frequency of approximately 4MHz in PWM mode. Output ripple is minimized, with typical values of 20mVpp in HyperLight Load mode and 3mV in full PWM mode.
The MIC23250 is designed for compact designs, utilizing small external components like a 1µH inductor and a 4.7µF output capacitor. It is available in a 2mm x 2mm Thin MLF® package, enabling a sub-1mm height solution. The operating junction temperature range is -40°C to +125°C.
This regulator is well-suited for portable electronic devices, including mobile handsets, media players, GPS devices, digital cameras, and USB-powered products.
