SC183C POWER MANAGEMENT Features                    2.5MHz, 2A Synchronous Step-Down Regulator Description The SC183C is a 2A synchronous step-down regulator designed to operate with an input voltage range of 2.9 to 5.5 Volts. The device offers fifteen pre-determined outputs voltages via four control pins programmable from 0.8 to 3.3 Volts. The control pins allow for on-the-fly voltage c hanges, enabling system designers to implement dynamic power savings. The SC183C is also capable of adjusting output voltage via an external resistor divider. The device operates with a fixed 2.5MHz oscillator frequency, allowing the use of small surface mount external components. Connecting CTL0 — CTL3 to logic low forces the device into shutdown mode reducing the supply current to less than 1µA. Connecting any of the control pins to logic high enables the converter and sets the output voltage according to Table 1. Other features include undervoltage lockout, soft-start to limit in-rush current, and over-temperature protection. The SC183C 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. VIN Range: 2.9 – 5.5V VOUT Options: 0.8 - 3.3V Up to 2A Output Current Ultra-Small Footprint,
