Overview
MIC2176-1/-2/-3 Wide Input Voltage, Synchronous Buck Controllers Featuring Adaptive On-Time Control Hyper Speed Control™ Family General Description The Micrel MIC2176-1/-2/-3 is a family of constant-frequency, synchronous buck controllers featuring a unique digitally modified adaptive ON-time control architecture.
The MIC2176 family operates over an input supply range of 4.
5V to 75V and can be used to supply up to 15A of output current.
The output voltage is adjustable down to 0.
8V with a guaranteed accuracy of ±1%, and the device operates at a constant switching frequency of 100kHz, 200kHz, and 300kHz.
Micrel’s Hyper Speed ControlTM architecture allows for ultrafast 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 MIC2176 offers a full suite of protecti...
