DC DC Converters

SKMW20F-03 is a high-frequency DC/DC converter, which is mainly used in applications such as LED lighting, TD-SCDMA base stations, and industrial computers.

Featureing a wide input voltage range operating from 4.5V to 36V, SKMW20F-03 is capable of providing a stable output currents up to 19.2A. It also features high efficiency up to 96%, low output ripple, low no-load current, and excellent EMC performance.

In terms of operation, SKMW20F-03 uses Pulse Width Modulation (PWM) to convert input dc voltage to an adjustable output dc voltage. This technique is used to control the power and transfer it from input to output. The PWM acts like a switch, with open and closed states. When it is in the open state, no current flows and when it is in the closed state, current flows from the input to the output. The average voltage at the output is dependent on the duty cycle of the PWM.

To increase the switching frequency of the PWM and thus reduce the size of the inductor, SKMW20F-03 employs a full bridge LCC Resonant Converter topology. The LCC Resonant Converter uses a capacitive element to create an oscillating circuit which results in a high switching frequency. This high switching frequency increases the efficiency of the converter and reduces the size of the inductor.

SKMW20F-03 also utilizes advanced control and protection features such as constant current control, constant voltage control, over-temperature protection, short-circuit protection, open circuit protection, and output over-voltage protection.

The SKMW20F-03 is an ideal solution for applications requiring high current in a compact design. It is designed to meet strict safety requirements, making it suitable for use in medical, automotive, industrial, and lighting applications.

Overall, SKMW20F-03 is a high efficiency, high power, and high performance DC/DC converter. It is suitable for a wide variety of applications, thanks to its wide input voltage range, high output current capability, and advanced control features.
