The AP1510SG-13 is a DC to DC Switching Regulator from the product family of regulators from the Global Power IC supplier Anpec Electronics Corporation. It is a power management IC (PMIC) solution for modern circuit designs such as embedded systems, consumer electronics, and automotive electronics that are designed to shrink component counts and design time while increasing system efficiency. This PMIC is well-suited for battery-powered systems.

Applications

The AP1510SG-13 is designed for applications such as embedded systems, consumer electronics, and automotive electronics, where space saving and efficiency are the main design goals. It is suitable for applications such as ultra-compact systems, portable devices, PDAs and notebook computers, where low power consumption is desired. The AP1510SG-13 is also suitable for powering up industrial microcontrollers. Other applications include high current/low drop out linear regulators, DC/DC converters, post regulation, step-up/step-down converters, voltage connectors and active clamp flyback converters.

Features

The AP1510SG-13 is an advanced DC to DC switching regulator. It offers an effective solution for maintaining constant input voltage, reducing the output ripple and noise, and providing efficient voltage transformation. Its features include an ultra-low quiescent current (37 μA at 2.1 V, 75 Hz DC/DC), an adjustable frequency from 50 KHz to 250 KHz, and a low dropout voltage of 0.5 V. It also features a 1 MHz reference oscillator and provides a low startup current of 1 μA. The AP1510SG-13 has an output voltage accuracy of ±2%, and a maximum output current of 1.2 A. It has a miniature SMD SOIC-8 package.

Working Principle

The AP1510SG-13 is a step-down switching regulator that works based on the principle of PFM (Pulse Frequency Modulation) control to optimize efficiency and reduce the output noise. The device uses an internal 1 MHz reference oscillator to generate PFM pulses. The combination of the reference oscillator and the PFM enable the device to accurately adapt to the load demands and maintain a constant output voltage with minimal ripples and noise. The combination of the reference oscillator and the PFM also enables the device to deliver high efficiency, low quiescent current, and low DCR output.

The AP1510SG-13 features an adjustable frequency, so that users can tune the frequency output to suit different applications. The device is designed to withstand over-temperature and ESD (electrostatic discharge) protection, making it a suitable choice for high-reliability systems. To further improve the power-saving capabilities, the AP1510SG-13 provides an enable pin, allowing the user to shut down the device completely when low power consumption is required.

Conclusion

The AP1510SG-13 from Anpec Electronics Corporation is a DC to DC switching regulator that is ideal for embedded systems, consumer electronics, and automotive electronics, where space saving and efficiency are important design goals. It is designed with an ultra-low quiescent current, adjustable frequency, low dropout voltage, low startup current, and ±2% accuracy. It is also designed to withstand over-temperature and ESD protection, and features an enable pin for low power consumption when needed. The AP1510SG-13 offers an effective solution for maintaining constant voltage with minimal ripple and noise, while providing efficient voltage transformation.
