Features and Applications

The MIC27600YJL is a constant-frequency, synchronous buck regulator featuring a unique digitally modified adaptive on-time control architecture. The MIC27600 operates over an input supply range of 4.5V to 36V and provides a regulated output of up to 7A 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 300kHz.

Micrel’s 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 digitally modified adaptive tON ripple control architecture combines the advantages of fixed-frequency operation and fast transient response in a single device.


  • Hyper Speed Control™ architecture enables

    • Small output capacitance
  • 4.5V to 36V voltage input
  • Adjustable output from 0.8V to 5.5V (VHSD ≤ 28V)
  • Adjustable output from 0.8V to 3.6V (VHSD ≤ 36V)
  • ±1% FB accuracy
  • Any Capacitor™ Stable - Zero-ESR to high-ESR
  • 7A output current capability, up to 95% efficiency
  • 300kHz switching frequency
  • Internal compensation, 6ms Internal soft-start
  • Foldback current-limit and “hiccup” mode short-circuit protection
  • Thermal shutdown
  • Supports safe startup into a pre-biased load
  • –40°C to +125°C junction temperature range
  • 28-pin 5mm – 6mm MLF® package
