Working Principle

SC196AMLTRT is a high performance, monolithic, stepdown DC-DC converter. It utilizes high-efficiency pulse width modulation (PWM) to deliver adjustable voltage output from a +5V, 10A power source. The output voltage can be programmed by adjusting the FB pin voltage, and is adjustable from 0.6V to 50V.A soft-start time of 250ns is also available. This voltage regulation circuit also includes short-circuit, over-voltage and over-temperature protection to improve system reliability.

SC196AMLTRT\'s operating principle is based on the PWM switching technique. The integrated buck regulator utilizes the PWM technology to achieve highly efficient voltage regulation. The integrated switch and synchronous rectifier are utilized to control the output voltage. A trimmed reference voltage ensures output voltage accuracy.

When the output voltage is not within the protected range, the internal control system will go into overvoltage protection or overcurrent protection mode. The output voltage will be regulated to the low voltage or high voltage threshold. In the case of a short-circuit condition, the integrated switch will be disabled and the output voltage will drop to 0.

The dynamic response and the transient performance of SC196AMLTRT are excellent. It features high efficiency thanks to the integrated buck regulator architecture. The output voltage can be adjusted within a wide range by programming the FB pin voltage. A soft-start time of 250ns is available, allowing for quick and smooth power up. The short-circuit, over-voltage and over-temperature protection also improve system reliability.

Conclusion

SC196AMLTRT is a highly efficient and cost-effective buck switching regulator from Monolithic Power Systems Inc. An adjustable voltage output can be obtained from a +5V, 10A power source. It is well-suited for a wide range of industrial and embedded systems applications, including low power microprocessor systems, antennas and other redundant load applications, automotive applications, computer systems, portable devices, industrial control applications, telecommunications and networking equipment and consumer electronics. The regulator utilizes high efficiency PWM buck switching to deliver adjustable output voltage, and offers short-circuit, overvoltage and overtemperature protection.
