.Data Sheet.co.kr 7A Hyper Speed Control TM Synchronous DC-DC Buck Regulator Super Switcher IITM General Description The Micrel MIC26600 is a constant-frequency, synchronous buck regulator featuring a unique digitally modified adaptive ON-time control architecture. The MIC26600 operates over an input supply range of 4.5V to 26V and provides a regulated output at up to 7A of output current. The output voltage is adjustable down to 0.8V with a typical accuracy of ±1%, and the device operates at a switching frequency of 300k Hz. Micrel’s Hyper Speed Control TM architecture allows for ultrafast transient response while reducing the output capacitance and also makes (High VIN)/(Low VOUT) operation possible. This digitally modified adaptive t ON ripple control architecture bines the advantages of fixed-frequency operation and fast transient response in a single device. The MIC26600 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, fold-back current limit, “hiccup” mode shortcircuit protection and thermal shutdown.
