MIC2125 and MIC2126 are constant-frequency synchronous buck controllers featuring a unique adaptive ON-time control architecture. The MIC2125/6 operates over an input voltage range from 4.5V to 28V and can be used to supply load current up to 25A . The output voltage is adjustable down to 0.6V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200kHz to 650kHz.
HyperLight Load® architecture provides the same high efficiency and ultra-fast transient response as the Hyper Speed Control® architecture under the medium to heavy loads. It also maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous conduction mode operation.
The MIC2125/6 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, "hiccup" mode short-circuit protection, and thermal shutdown.
Hyper Speed Control® architecture enables:
High delta-V operation (VIN = 28V and VOUT = 0.6V)
Any Capacitor™ stable
4.5V to 28V input voltage
Adjustable output voltage from 0.6V to 24V
200kHz to 650kHz programmable switching frequency
HyperLight Load® (MIC2125)
Hyper Speed Control® (MIC2126)
Enable input and power good output
Built-in 5V regulator for single-supply operation
