DC to DC converters are a type of power supply that, unlike a linear power supply, use a switching regulator instead of a linear regulator. A linear regulator regulates the output of a power source by dissipating the excess voltage as heat, while a switching regulator outputs a regulated voltage over a wide range of input voltages and, unlike a linear voltage regulator, does not require a heat sink. The ATS020A0X3-SRPHZ is a DC DC converter from the Toshiba Corporation, and the following sections explain its application field and the working principle.

Application Field

The ATS020A0X3-SRPHZ is a 12V-input, 0.5A output DC DC converter, designed for use in automotive applications. It is mainly used for automobile electronics applications, such as electronic control unit (ECU) power supply, instrument cluster power supply, and motor control circuit power supply. The converter has a wide input voltage range from 4V to 16V, making it suitable for a variety of automotive power sources. The converter also has an operating temperature range of −40 °C to +125 °C, which makes it ideal for use in harsh environments. The device is certified according to ISO/IEC-7637-2, which is a quality assurance for electronic components used in in-vehicle applications.

Working Principle

The ATS020A0X3-SRPHZ uses a switching regulator to convert the input voltage to a regulated output voltage. The switching regulator works by rapidly switching a power transistor between an ON state and an OFF state. The power transistor is connected between the input voltage and ground, and by rapidly switching it ON and OFF, the average voltage across it is equal to the input voltage. The voltage across the transistor is then used to drive an inductor, which stores energy in a magnetic field and then releases it in the form of a current that is equal to the input voltage. This current is then used to power the output device, which regulates the output voltage to the desired level. The regulator also uses a feedback circuit to ensure that the output voltage remains constant, regardless of changes in the input voltage or load.

Conclusion

The ATS020A0X3-SRPHZ is a DC DC converter from the Toshiba Corporation, designed for use in automotive applications. It has a wide input voltage range from 4V to 16V, making it suitable for a variety of automotive power sources, and it has an operating temperature range of −40 °C to +125 °C, making it suitable for harsh environments.
