The SC187 is a 4A synchronous step-down regulator designed to operate with an input voltage range of 2.9V to 5.5V. The device offers fifteen pre-determined output voltages via four control pins programmable from 0.8 to 3.3 Volts. The control pins allow for on-the-fly voltage changes, enabling system designers to implement dynamic power savings. The device is also capable of adjusting output voltage via an external resistor divider. The SC187 operates in PWM mode with fixed 2.2MHz oscillator frequency, allowing the use of small surface mount external components.Connecting the control pins 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 under-voltage lockout, programmable soft-start to limit in-rush current, power good indicator, over-temperature protection, and output short circuit protection. The SC187 is available in a thermally-enhanced, 3 x 3 x 0.6 (mm) MLPQ-UT16 package.
