The SC286 is a dual channel 4A synchronous step-down regulator designed to operate with an input voltage range of 2.9V to 5.5V. Each channel offers fifteen predetermined output voltages via separate 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 SC286 is optimized for maximum efficiency over a wide range of load currents. During full load operation, the device operates in PWM mode with fixed 1.6MHz oscillator frequency, allowing the use of small surface mount external components. As the load decreases, the regulator will transition into Power Save mode maintaining high efficiency.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 SC286 is available in a thermally-enhanced, 4 x 4 x 0.6 (mm) MLPQ-UT28 package and has a rated temperature range of -40 to +85°C.
