MIC33050 Datasheet 4mhz Internal Inductor Pwm Buck Power Module

Manufacturer: Microchip Technology

Overview: MIC33050 4 MHz Internal Inductor PWM Buck Power Module with HyperLight.

General Description

The MIC33050 is a high-efficiency 600 mA PWM synchronous buck (step-down) regulator with internal inductor featuring HyperLight Load®, a switching scheme that offers best-in-class light load efficiency and transient performance while providing very small external components and low output ripple at all loads.

The MIC33050 also has a very low typical quiescent current of 20 µA and can achieve over 85% efficiency even at 1 mA.

In contrast to traditional light load schemes, the HyperLight Load® architecture does not trade off control speed to obtain low standby currents and in doing so, the device only needs a small output capacitor to absorb the load transient as the powered device goes from light load to full load.
