DC DC Converters

DC-DC converters are electrical circuits designed to convert a DC voltage from one magnitude to another, and output an isolated DC voltage from an input DC voltage. The SQM48S20010-PS0P is a DC-DC power converter with a wide range of potential applications. This article will discuss the SQM48S20010-PS0P application field and working principle.

Application Field

The SQM48S20010-PS0P is an ultra-high-efficiency DC-DC converter specifically designed to provide efficient power conversion for applications requiring small footprints. These applications include telecom systems, medical supplies, automotive applications, industrial systems, on-board vehicle charging, instrumentation, AIDC systems, and more. It is also suitable for applications in the open air environment, which requires isolation and can withstand large temperature fluctuations.

Working Principle

The SQM48S20010-PS0P uses a full-bridge rectifier, combined with a switching controller, to convert a wide range of input DC voltages into an isolated DC output with a high efficiency of 92%. The TFN (Thin Film Network) technology used in the device reduces its profile to just 0.45 inch, making it suitable for applications with large operating temperatures. The device also features a low ripple voltage, fast transient response, and a wide input voltage range of 48V to 160V.

The SQM48S20010-PS0P uses soft-start technology to provide reliable start-up protection and a built-in active current limit, eliminating the need for external current limiting resistors. This provides a safe and reliable power supply for power systems with a high level of protection. The device also features over-temperature, over-voltage, over-current, and short-circuit protection.

The SQM48S20010-PS0P is a high performance, cost-effective DC-DC power converter suitable for a wide range of applications. Its small size and high efficiency make it an ideal choice for space-restricted and energy-sensitive applications. It has a wide range of protection features enabling it to operate reliably and safely under harsh conditions.
