The device requires minimal external components for a complete step down regulator solution. The output voltage is factory predetermined with an available range of 1.0V to 3.3V. The SC3102 is optimized for maximum efficiency over a wide range of load currents. During full load operation, the SC3102 operates in forced PWM mode with a fixed 1.5MHz oscillator frequency, allowing the use of small surface mount external components. As the load decreases, the regulator has the option to transition, via the MODE pin, into forced Power Save mode to maximize efficiency or to stay in forced PWM mode. The SC3102 offers output short circuit and thermal protection to safe guard the device under extreme operating conditions. The enable pin provides on/off control of the regulator. When connected to logic low, the device enters shutdown and consumes less than 1μA of current. Other protection features include programmable soft-start with Power Good indicator, over voltage protection and under voltage lockout. The SC3102 is available in a thermally-enhanced, 3mm x 3mm x 0.6mm MLPQ-UT16 package and has a rated temperature range of -40 to +85°C.
