MIC24085
18V, 3A, 1MHz, High-Performance, Integrated FET Buck
Regulator in Tiny 3mm × 3mm QFN
General Description
Micrel’s MIC24085 is a constant-frequency, current-mode PWM buck
regulator with integrated switchers.
The MIC24085 is targeted for cost-sensitive and highperformance applications.
The MIC24085 operates over a supply range of 4.
5V to 18V at a fixed 1MHz switching frequency and can be used to provide up to 3A of output current.
The output voltage is adjustable down to 0.
9V.
The MIC24085 provides the features of low standby current at 10µA, device enable, input undervoltage lockout, and output voltage monitoring.
The part also provides fault protections of overcurrent and overtempe...
