MURATA PE24108 3.3 Vin two-stage buck regulator IC with integrated switching field-effect transistors (FETs) is suitable for low-profile < 1.2mm applications. Solution allows the power train to be mounted on the underside of the pcb, in close proximity to the main DSP/ASIC core, reducing I2R losses and noise pick-up. Offered in a 4.0 × 3.2 mm QFN package, device is designed to operate over an input voltage range of 3.0V–3.6V and has programmable output voltage of 0.35V–1.0V at up to 10 amps. Product is suitable for 3.3V point-of-load applications where high efficiency, low profile, low ripple and EMI are essential. The output can be precisely adjusted via external DAC during operation.
