... NCP1540 Product Preview 3.5 A High Efficiency Step-Down DC-DC Converter The NCP1540 is a high efficiency step-down buck regulator with an integrated high side MOSFET. An internal 110 mW N-channel MOSFET power switch enables delivering 3.5 A continuous load currents with up to >90% efficiency. The NCP1540 features current-mode pulse-width modulation (PWM) control with feed forward compensation and operates at fixed switching frequency of 385 kHz ...

... The NCP1540 is a current-mode step-down regulator. It regulates input voltages from 4 down to an output voltage as low as 1.2 V, and is able to supply continuous load current. The NCP1540 uses current-mode control to regulate the output voltage. The output voltage is measured at FB through a resistive voltage divider and amplified through the internal error amplifier ...
