MIC24055
12V, 12A High-Efficiency Buck Regulator SuperSwitcher II
General Description
Features
The Micrel MIC24055 is a constant-frequency, synchronous buck regulator featuring a unique adaptive on-time control architecture.
The MIC24055 operates over an input supply range of 4.
5V to 19V and provides a regulated output of up to 12A of output current.
The output
voltage is adjustable down to 0.
8V with a guaranteed accuracy of ±1%, and the device operates at a switching frequency of 600kHz.
• Hyper Speed Control architecture enables - High delta V operation (VIN = 19V and VOUT = 0.
8V) - Small output capacitance
• Input
voltage range: 4.
5V to 19V • Output current up to 12A • Up to 95% effi...
