The TPS62236EVM-574 is an evaluation board designed to evaluate the TPS62236 dual-channel, low-dropout (LDO) voltage regulator. It provides a convenient way of rapidly prototyping the device in its intended application circuits. The TPS62236EVM-574 is an evaluation board targeted for off-line power supply applications.

The TPS62236EVM-574 evaluation board has two outputs, each with its own output voltage adjustment terminals. The first channel is connected to a buck regulator for 300mA output current and voltage ranging from 0.6V up to 5V. The second channel is connected to a charge pump regulator, capable of providing up to 360mA output current and voltage ranging from 2.7V up to 5V. Both outputs can be individually turned on and off via the control pins.

The TPS62236EVM-574 features wide-input voltage range (9V–65V), a protection circuit outputting crowbar current (3A) and allowing users to avoid latent short circuits in their designs. Additionally, this board includes three built-in logic comparators, providing guard-rail protection. This makes the TPS62236EVM-574 suitable for applications requiring extra operational and safety features.

The TPS62236EVM-574 evaluation board is controlled by either a stand-alone step-up/down converter or external circuitry, such as a power microcontroller. The onboard diode bridge rectifier converts the AC mains input to the required DC input. The onboard PWM controllers and integrated MOSFETs provide pulse-width modulation (PWM) to control the buck or charge-pump regulator. The integrated LDO provides the required output voltage for the buck or charge-pump regulator.

The TPS62236EVM-574 provides a wide range of options for the output voltage, power, and control features, allowing users to customize their design to their needs. The onboard protection circuits and logic comparators ensure a safe operation. The board can be used for a variety of off-line power supply applications, such as AC-DC adapters, battery chargers, and UPS systems.

Overall, the TPS62236EVM-574 evaluation board is a highly reliable and feature-rich evaluation board for off-line power supply applications. It provides an effective way to quickly and easily evaluate the TPS62236 dual-channel, low-dropout (LDO) voltage regulator and its intended application circuits. This evaluation board can be used to develop and refine reliable, safe, and energy-efficient off-line power supply systems.
