SY8113BADC

The SY8113BADC is the TSOT-23-6 ordering code for the Silergy SY8113B, a 3 A synchronous step-down converter. It accepts a 4.5 V to 16 V input, regulates against a 0.6 V reference held to +/-1.5% and uses an instant-PWM constant-on-time style architecture for fast transient response, integrating both power MOSFETs so the external circuit is essentially an inductor and divider. A full 3 A rail from a six-pin package is the selection point: it powers set-top boxes, routers, access points and LCD equipment from 12 V-class adapters without the board area of a controller-plus-FET design. Selection advice: fix the output with the feedback divider at design time and check inductor saturation at the 3 A ceiling with margin; this ADC package code is the TSOT-23-6 form, so do not substitute SOT-23 lookalikes without checking the Silergy pinout.
