PAM2309AABADJR

PAM2309AABADJR application field and working principle

The PAM2309AABADJR, released by MORNSUN, is categorized into Power Management and Integrated Circuits (PMICs) – Voltage Regulators – DC DC Switching Regulators. It is used as a DC-to-DC converter, primarily in portable devices.

The PAM2309AABADJR is a switching regulator that includes two stages: a synchronous rectifier buck converter and an offset control boost converter. According to the manufacturer, the synchronous rectifier topology is extremely space-saving and efficient. This is achieved through the integration of power FETs and integrated Schottky diodes, allowing for high-precision DC-DC conversion.

In addition, the device features a wide input voltage range (2.0 V to 5.5 V), accepts input currents up to 1A and provides output currents up to 900mA. It also has an automatic power-saving system and overcurrent protection which automatically switches to low-power mode when the current is too high.

The PAM2309AABADJR has some other features as well. It supports wide-input voltage range (2.0V to 5.5V), supports 7 output voltage settings up to 3.3V and wide output voltage range (1.0V to 3.3V). Its low quiescent current mode (max. 40µA) enables it to be used in battery-powered applications. It also allows the output voltage to be adjusted by I2C port. These features make it suitable for use in extremely space-constrained applications like digital cameras, MP3 players, WiFi/Bluetooth modules, power meters, and mobile phone chargers.

The PAM2309AABADJR is a very efficient device with a high power efficiency. It achieves up to 95% efficiency over its full output range and allows for a wide operating range from 10mohm to 1ohm of external synchronous rectifier FETs, allowing it to support a wide range of load conditions. The device also features a high-resolution switching frequency control technology which allows for a wide range of output frequencies within the range of 500 kHz to 1.5 MHz.

In summary, the PAM2309AABADJR is a DC-to-DC converter that is suitable for use in portable devices such as cameras and mobile phone chargers. Its high efficiency, wide input voltage range and low quiescent current make it the ideal choice for these applications. It also features a wide range of output frequencies, adjustable output voltage and a high-resolution switching frequency control technology.
