MIC4930 Datasheet Hyper Speed Control 3a Buck Regulator

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: MIC4930 Hyper Speed Control™ 3A Buck Regulator General.

General Description

The MIC4930 is a high-efficiency, 3A synchronous buck regulator with ultra-fast transient response perfectly suited for supplying processor core and I/O voltages from a 5V or 3.3V bus.

The MIC4930 provides a switching frequency up to 3.3MHz while achieving peak efficiencies up to 95%.

An additional benefit of high-frequency operation is very low output ripple voltage throughout the entire load range with the use of a small output capacitor.

Key Features

  • Input voltage: 2.7V to 5.5V 3A output current Up to 95% efficiency Up to 3.3MHz operation Safe start-up into a pre-biased output Power Good output Ultra-fast transient response Low output voltage ripple Low RDS(ON) integrated MOSFET switches 0.01µA shutdown current Thermal shutdown and current limit protection Output voltage as low as 0.7V 3mm × 4mm DFN-10L.
  • 40C to +125C junction temperature range Appl.
