The UCC28230PW is a fully-integrated high-side switch control IC with a 2.5V to 5.5V wide operating range. It is designed to provide a complete, low-power solution for controlling DC-DC power conversion. The UCC28230PW is part of Texas Instruments’ Power Management IC (PMIC) family and falls into the Voltage Regulators – DC DC Switching Controllers category. This application note explores the features and benefits of the UCC28230PW, its application field, and its working principle.The UCC28230PW is an advanced high-side switch control IC with open drain architecture that can be used in a variety of switching application and provides low power consumption and high efficiency. It is ideal for applications such as portable electronic devices, charging systems, audio, and automotive systems. The UCC28230PW\'s open drain architecture allows it to switch to a higher voltage than the highest powered source, which makes it great for applications that require power conversion between 2 different voltage sources. The 20-V maximum switch voltage allows it to be used in a wide range of applications.The UCC28230PW offers a variety of features that make it an ideal choice for applications in its field. The UCC28230PW includes an on-chip oscillator and current-sense circuitry to provide a low-power solution for integrating switch control circuitry. Additionally, a high voltage bootstrap circuit, incorporated in the device, increases the available switch voltage to 20V. The open-drain device also features multiple fault protection modes to protect against damage from overcurrent, overvoltage, short circuits, and overtemperature. In addition, the device features a single-wire interface for easy integration into existing systems.The UCC28230PW follows a two-step switching process for controlling the DC-DC conversion. The two steps are the start-up phase and the steady-state phase. The start-up phase is used to safely and reliably bring the switch voltage to the target voltage without exceeding the maximum allowable voltage. The steady-state phase is used to maintain and regulate the switch voltage as required.In the start-up phase, the UCC28230PW\'s internal oscillator is used to control the turns-on of the high-side switch. A comparator monitors the ramp of the output voltage and the internal oscillator adjusts the frequency to bring the output voltage to the target voltage without exceeding the maximum switch voltage. When the target voltage is reached, the UCC28230PW changes to the steady-state phase and the frequency of the internal oscillator is increased until the current limit is reached, at which point the switch is turned off. The frequency is then adjusted to maintain the target voltage as the load current changes.The UCC28230PW provides a complete and efficient solution for DC-DC power conversion in a variety of applications. The device\'s low-power requirements and integrated protection features make it an ideal choice for high-side switch control. The open-drain architecture allows it to switch to higher voltages than the highest powered source, which makes it ideal for applications that require power conversion between two different voltage sources. Additionally, the UCC28230PW offers robust protection features, such as overcurrent, overvoltage, short circuit, and overheat protection, to ensure reliable operation. Finally, with its single-wire interface, the UCC28230PW can be easily integrated into existing systems.
