Status: In Production
The 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 allows for ultra-fast transient response while reducing the output capacitance and also makes (High VIN)/(Low VOUT) operation possible. This adaptive tON ripple control architecture combines the advantages of fixed-frequency operation and fast transient response in a single device.
The MIC24055 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include under voltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, foldback current limit, "hiccup mode" short-circuit protection and thermal shutdown. An open-drain power good (PG) pin is provided. Also see the 12A HyperLight Load® part, MIC24056.
The MIC24055 DC/DC synchronous buck regulator operates over an input supply range of 4.5V to 19V and provides a regulated output at up to 12A of load current. The output voltage is adjustable down to 0.8V with a typical accuracy of ±1%. The device operates at a switching frequency of 600kHz, which remains relatively constant with changes in input voltage and output load. The basic parameters of...
