MIC26400 Buck Regulator
Microchip’s Hyper Speed Control™ architecture allows for ultra-fast transient response
Microchip's MIC26400 is a constant-frequency synchronous buck regulator featuring a unique digitally modified adaptive ON-time control architecture. The MIC26400 operates over an input supply range of 4.5 V to 26 V and provides a regulated output at up to 5 A of output current. The output voltage is adjustable down to 0.8 V with a typical accuracy of ±1%, and the device operates at a switching frequency of 300 kHz.
Microchip’s Hyper Speed Control TM architecture allows for ultra-fast transient response while reducing the output capacitance and also makes (High VIN)/(Low VOUT) operation possible. This digitally modified adaptive tON ripple control architecture combines the advantages of fixed frequency operation and fast transient response in a single device.
The MIC26400 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage 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.
