The MIC23250-F4YMT-TR from Microchip Technology is a high-efficiency, 4MHz dual synchronous buck regulator with HyperLight Load mode. This device is designed for applications requiring efficient power delivery at both light and heavy loads, such as mobile handsets and portable media players.
Key electrical specifications include a wide input voltage range of 2.7V to 5.5V, with each of the two outputs capable of delivering up to 400mA. The regulator operates at a nominal switching frequency of 4MHz in PWM mode, offering peak efficiencies up to 94% and maintaining 85% efficiency at 1mA load. It features a low quiescent current of 33µA with both outputs enabled.
The device is housed in a compact 12-MLF™ (2.5x2.5mm) package, suitable for space-constrained designs. It requires minimal external components, including a 1µH inductor and a 4.7µF output capacitor, enabling a sub-1mm height solution. The operating junction temperature range is -40°C to +125°C.
This buck regulator is ideal for applications demanding ultra-fast transient response and low output ripple voltage, making it well-suited for supplying processor core voltages. Its design facilitates efficient power management in portable electronic devices.
