Working Principle

The S-8337ACGB-P8T1G Power Supply is designed to provide an output voltage that is stable and has low ripple noise. The device operates in peak current mode (PCM) regulation in order to minimize the power consumed.The device uses two inputs — a regulated voltage from a separate voltage regulator and an unregulated voltage from an external power source. The S-8337ACGB-P8T1G integrated circuitry senses the input ripple, compares it to the output voltage, and adjusts the output voltage accordingly. This way, the device is able to maintain the output voltage within a desired range.The S-8337ACGB-P8T1G has an integrated over-temperature protection circuit that increases the current limit when the temperature of the device exceeds a predetermined threshold. This prevents the device from overheating in the presence of an excessive load.

Conclusion

The S-8337ACGB-P8T1G is an effective low cost, high efficiency dual input regulator designed for low-power applications. The device is capable of regulating in constant voltage (CV), constant current (CC) and peak current mode (PCM) operation, and features a programmable output voltage range, adjustable current limit, and over-temperature protection. This device is ideal for powering integrated circuits, telecoms, medical equipment and other applications related to battery-based DC/DC converters and ac-dc adapters.
