SC185

SC185 POWER MANAGEMENT Features Description 4A Synchronous Step-Down Regulator  VIN Range: 2.9 – 5.5V  VOUT Options: 1.0V to 3.3V  Up to 4A Output Current  Ultra-Small Footprint, <1mm Height Solution  1.5MHz Switching Frequency The SC185 is a 4A synchronous step-down regulator designed to operate with an input voltage range of 2.9V to 5.5V. The device requires only three external filter components for a complete a step down regulator solution. The output voltage is factory predetermined with an available range of 1.0V to 3.3V.  Optional Power Save Mode Operation  Efficiency Up to 95%  Low Output Noise Across Load Range  Excellent Transient Response  Start Up into Pre-Bias Output  100% Duty-Cycle Low Dropout Operation  <1µA Shutdown Current  Externally Programmable Soft Start Time The SC185 is optimized for maximum efficiency over a wide range of load currents. During full load operation, the SC185 operates in PWM mode with fixed 1.5MHz o...
