Description: 2.25MHz 600mA Synchronous Step-Down Converter

Features

* VIN Range 2.7V to 5.5V
* VOUT Range 0.6V to 5.5V (100% Duty Ratio Operation)
* VREF = 0.6V
* ISD ≤ 5μA (VEN = 0V)
* Current Mode Control, Internal Compensation
* Fixed FSW 2.25MHz
* RDS(ON) 230mΩ HS/250mΩ LS (P-MOSFET/ N-MOSFET)
* Enable (VIH = 1V, VIL = 0.4V)

Applications

* The RT2657BQ enters Low Dropout Mode when normal Pulse -Width Mode cannot provide regulated output voltage by continuously turning on the high-side P-MOSFET. The RT2657BQ enters shut-down mode and consumes less than 5μA when the EN pin is pulled low. The switching ripple is easily smoothed-out by s
