Description
The MIC4520/MIC4521 is an IntelliMOS power stage family capable of delivering up to 20A in a compact 4 x 6mm TQFN package. The MIC4521 is a two phase power stage (includes MOSFET drivers and power MOSFETs) featuring integrated current and temperature sensing. The MIC4521 can be interfaced with a single phase controller (such as Micrel’s MIC2111) to build a complete high current and high performance power converter. The MIC4520 is a single phase power stage that can operate with a single phase or multiphase controller. The MIC4520/MIC4521 utilizes Micrel’s high performance FETZilla™ DMOS technology to achieve high efficiency (over 90% peak).
Features
- 7V to 16V input voltage range
- 3.3V logic tri-state PWM signal 560kHz to 1.2MHz switching frequency range
- 90% efficiency for a 12V to 2.5V/20A conversion
- Integrated temperature sensing (10mV/°C)
- 2-phase power stage operates from 1-phase controller (MIC4521)
- Mode selection pin for CCM/DCM operation
- Single tri-state PWM
- Integrated MOSFETs, drivers, and thermal monitors
