The SY26512A high efficiency, high power density, synchronous step-up regulator operates using adaptive constant off-time and current mode control, a wide input voltage range from 2.9V to 16V. It integrates switches with low RDS(ON) to minimize conduction loss.

The SY26512A features selectable PFM/PWM light load operation mode, cycle-by-cycle peak current limit, and internal soft-start to limit inrush current. The programmable pseudo-constant frequency reduces output voltage ripple and enables using smaller external capacitors and inductor.

The programmable peak current limit enables using smaller inductor sizes for applications that require lower output current.

The SY26512A is available in a compact QFN, 3mm×3mm 20 pin package.
