AP2815BMM-G1 is a power distribution switch, load driver, and integrated high efficiency, high performance, step-up DC-DC converter (buck-boost converter) with built-in current-mode control and PMOS power switch. It is designed and intended for use in medium power system applications, including industrial, Automotive, lighting, and audio applications.

The AP2815BMM-G1 integrates a pulsewidth modulated (PWM) current-mode controller, a PMOS power switch, an undervoltage lockout (UVLO) block, an overvoltage protection (OVP) block, as well as thermally protected wide operating temperature range. The AP2815BMM-G1 offers up to a 4A peak output current with an adjustable output voltage range of 0.8V to 6V.

The AP2815BMM-G1 is able to provide efficient, accurate, and low-cost solutions for high current switching, current-mode control loop, and high-side power switching. It can automatically reduce input voltage to maximum efficiency when supplying output power. This is done by controlling VIN and PWM currents with accurate phase current sensing and current foldback. This feature improves the efficiency of the AP2815BMM-G1 by ensuring that the input voltage is always kept between two points, allowing it to automatically compensate for the load current increase when load demand increases.

When load demand increases, the AP2815BMM-G1 automatically regulates the output voltage level by controlling the PWM duty cycle and operating frequency with accurate current sensing and current foldback. This feature also helps reduce the need for an external active role control circuit, as the AP2815BMM-G1 can dynamically adjust the system’s output voltage based on the load demand.

In addition, the AP2815BMM-G1 boasts of low ripple, low noise, and high power factor. It also features low quiescent current and low operating temperature, allowing it to efficiently deliver reliable and stable output power to the load. It also has an adaptive gate drive feature. This feature helps reduce gate drive power consumption and enables a higher operating frequency, allowing the AP2815BMM-G1 to achieve higher PWM efficiency.

Furthermore, the AP2815BMM-G1 integrates a power temperature compensation circuit. This helps the AP2815BMM-G1 to automatically compensate for the temperature drift and maintain the output voltage at a constant level. Finally, the AP2815BMM-G1 features fault protection, which helps protect the device from short circuit, undervoltage, overvoltage, and over current.

The AP2815BMM-G1 is quite a versatile product and is suitable for a wide range of medium power system applications, such as LED lighting systems, automotive applications, industrial applications, and audio applications.
