AP1520SL-13

AP1520SL-13 is a DC DC Switching Regulators that belongs to the Voltage Regulators within Power Management ICs (PMIC). It is designed to provide a high performance, cost-effective and user-friendly platform for mobile and battery power applications, such as portable audio and video players, electronic tools and PDAs.

AP1520SL-13 provides high-performance DC-to-DC conversion over a wide input range of up to 16.8V operation. This voltage regulator delivers up to 15A continuous output current and is able to regulate up to a maximum of 20A peak output current. It also has a high efficiency of up to 95%. With its wide input range and high switching frequency, AP1520SL-13 is able to minimize power dissipation and reduce the level of EMI.

The product features an accurate programmable switching frequency of up to 1MHz, and it can also be synchronized with an external clock. Furthermore, hot-switch output enable and programmable soft-start/soft-stop are built-in as well, which allows an easy operation. This product utilizes monolithic three-terminal linear integrated regulators which reduces external component cost and provides input overvoltage and output current protection.

AP1520SL-13 is widely used in applications such as portable audio and video players, electronic tools and PDAs. It is ideal for 3V to 8V output requirements. The device is designed to protect against input overvoltage and output current overload, and it can also be used in single-cell li-ion battery applications.

The working principle of the AP1520SL-13 is based on pulse width modulation (PWM) control. The PWM control is used to compare the output voltage with an internal reference, in order to adjust the duty cycle and output current accordingly. The regulator has a built-in regulator controller which monitors the input and output voltage and adjusts the output voltage as needed. This helps to ensure the desired output voltage is maintained even when there is a change in the input voltage.

The pulse width modulation control implemented in the AP1520SL-13 is able to achieve a high level of efficiency and maintain the output voltage at a stable level. In addition to its high efficiency, the device features a low noise performance, due to its low switching frequency. This ensures that the noise generated by the voltage regulator is kept at an acceptable level.

In conclusion, AP1520SL-13 provides high performance, cost-effective and user-friendly solution for DC-to-DC conversion applications. Its wide input voltage range, high switching frequency, integrated regulator controller and low noise performance make it an ideal choice for portable audio and video players, electronic tools and PDAs that require a high level of performance.
