MIC2125/6
28V Synchronous Buck Controllers
Featuring Adaptive ON-Time Control
Features General Description Hyper Speed Control Architecture Enables:
-High delta V operation (VIN = 28V and VOUT
= 0.6V)
-Any Capacitorв„ў stable 4.5V to 28V Input Voltage Adjustable Output Voltage from 0.6V to 24V 200 kHz to 750 kHz Programmable Switching
Frequency The MIC2125 and MIC2126 are constant-frequency
synchronous buck controllers featuring a unique
adaptive ON-time control architecture. The MIC2125/6
operate 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 В±1%. The device operates with
programmable switching frequency from 200 kHz to
750 kHz. Package Type пѓЈ 2015 Microchip Technology Inc. 16 15 14 13
