The AP3125BKTR-G1 is an integrated high performance advanced power management IC (PMIC) designed to effectively manage power for low power supply applications such as HDTVs and set top boxes. It is designed to regulate the output voltage of a DC-DC converter, and also provides advanced features such as a programmable power monitor, switching frequency, overvoltage, overcurrent, and thermal protection. The AP3125BKTR-G1 is available in an 8-pin and operates from 5V to 36V input, with a wide output range from 0.6V to 5V.

The AP3125BKTR-G1 is designed for offline switcher applications which consist of AC/DC converter, switchmode power supply and/or DC-DC converter. It integrates an easy-to-use integrated power management system (IPMS) to dynamically and efficiently manage the primary and secondary power states, while supporting a wide range of input and output voltages to meet the requirements of a wide range of applications. The AP3125BKTR-G1 also features a full feature enabling/disabling function, allowing the user to customize their power management scheme.

The AP3125BKTR-G1 integrates a constant on-time control scheme for the buck converter, allowing for high efficiency power conversion. In buck conversion mode, the device maintains a stable output voltage even under changing input and load conditions. The AP3125BKTR-G1 also supports a low power light load mode, in which the device will automatically reduce output voltage to a lower level when input or load conditions change, while maintaining output accuracy.

The AP3125BKTR-G1 includes a built-in overvoltage, overcurrent, and thermal protection. It provides a wide range of programmable protection thresholds to suit customer specific applications. The device also includes a high accuracy power monitor, which allows for monitoring of output power, input voltage and current, and load line regulation parameters, allowing for complete system performance monitoring.

The AP3125BKTR-G1 provides an easy-to-use programmable shutdown function, allowing the user to customize their power management scheme. It is designed for use in AC-DC converters, off-line switchers and other DC-DC applications, and is fully integrated for maximum system power efficiency. The AP3125BKTR-G1 is available in an 8-pin TSSOP package.
