The SC21150ACSTRT is a high power DC-DC switching regulator. It is one of the most efficient regulators in the market, with an average efficiency of over 95%. In addition, the SC21150ACSTRT has a wide operating range, allowing it to accommodate both low- and high-voltage inputs. It is also ideal for use in applications with high transient load demands.

The SC21150ACSTRT is a standard 3-A DC-DC step-down regulator with an adjustable output voltage range from 0.8 V to 11 V. It is capable of providing up to 20 W of power in continuous-conduction mode. The regulator supports a wide variety of input sources, ranging from 6 V to 24 V, and is designed to operate within a wide-ranging temperature environment, from −40 °C to +125 °C.

The SC21150ACSTRT utilizes a synchronous buck-conversion technique, which improves efficiency for a wide range of loads. The synchronous buck converter consists of two MOSFETs, one for the high-side switch and one for the low-side switch, both switching at the same frequency. The output voltage is regulated by the on-board PWM controller, which senses the output voltage and adjusts the duty cycle of theoscillator accordingly. The output voltage is adjusted via an external potentiometer.

The SC21150ACSTRT offers a wide range of protections, including over-voltage, under-voltage, over-current, and thermal/short-circuit protections, to help ensure system reliability. In addition, the regulator is capable of withstanding transients and EMI (electromagnetic interference) for safe operation in noisy environments. The device is also designed for low EMI noise and meets the EN55022 Class B EMI standard.

The SC21150ACSTRT is a powerful DC-DC switching regulator and is a perfect choice for many high-end applications such as industrial automation, medical-imaging, and telecom systems. The superior protection features, wide operating range, and high efficiency make it an ideal solution for many demanding applications.
