AP1512-12K5L-13

AP1512-12K5L-13 DC/DC switching regulators are a type of PMIC (Power Management Integrated Circuit) voltage regulator that provides a highly efficient power conversion solution, with low start up current and low output ripple. In the field of high power output applications such as server, notebook, and communication system power systems, they are the perfect choice.

The DC/DC switching regulators are able to convert a wide input voltage range, from 5V to 32V, and can output voltage from 0.9V – 5.5V. With an efficiency ranging from as low as 80% to even 96%, the AP1512-12K5L-13 device can achieve a powerful low power consumption. It is designed with a low output ripple and noise, which is exceptionally small and provides stable voltage output for an even more reliable power output.

The working principle of AP1512-12K5L-13 is based on a fixed frequency PWM (Pulse Width Modulation) operating in DC to DC buck mode. As the input voltage can vary in a wide range of up to 32V, balanced circuitry is implemented when the internal Schottky diode is reverse-biased, thus enabling the inductor to function as a ground reference voltage. During operation, the duty cycle of the PWM oscillator will be constantly adjusted in order to maintain a constant output voltage, while the output is achieved by the low-side switching MOSFET. When the external load of the device changes, the inductor current will have a corresponding change and feedback to the control IC, and with the compensation settings, the power inductor current is ideal, allowing for an optimal performance.

The AP1512-12K5L-13 comes with many protection features that is designed to ensure a safe and reliable operation. It is designed with a great overload protection and a wide wide-temperature range operation, from -40℃ to 125℃. It also has under voltage protection, improved electro-magnetic interference, and a soft-start feature which reduces the inrush current without the need for an external component.

The AP1512-12K5L-13 is the ideal solution for many applications needing an efficient and stable DC/DC switching regulator. It is widely used in server, notebook, desktop, and communication system power supplies, medical and automotive power supplies, and DC/DC buck converters in POE applications. With its wide input voltage range, low power consumption, and ultra low output ripple, the AP1512-12K5L-13 is suitable to provide reliable and efficient power conversion.
