AP7315D-285W5-7 is a linear voltage regulator belonging to PMIC - Voltage Regulators - Linear category. It is a two-phase, two-output voltage regulator with built in oscillator, enabling smooth circuit startup and dynamic frequency control to reduce EMI. This regulator provides two stable, low noise, low dropout (LDO) output voltages of 5.2V and 7.8V. UsageAP7315D-285W5-7 is typically used in applications such as high frequency digital portable electronics, set-top boxes, gaming consoles and other portable products that require both low noise and a compact form factor. It is designed for high frequency switching for high efficiency power supplies, and also in applications that require high speed response and low EMI characteristics.FeaturesThe AP7315D-285W5-7 has a wide input voltage range of 5 to 18V and is available in 5-pin SOT-23 and 6-pin SOT-25 package. The maximum output current of the device is based on the junction temperature, output voltage and airflow. It provides an adjustable output current limit and short circuit protection. The output voltage is adjustable from 4.4V to 8V and the current limit is adjustable from 0.225A to 3A.The device is also protected from over-voltage and thermal shutdown, making it suitable for applications with high power requirements.Working PrincipleAP7315D-285W5-7 is a two-phase linear voltage regulator. Its working principle is based on a switch-mode architecture, where both switching stages are controlled by a built-in oscillator. The oscillator frequency is adjustable between 300 kHz and 2.6MHz. The regulator generates a DC power supply using a Buck converter topology. It consists of two buck converters that are controlled in a complementary manner to generate two output voltages. The buck converter is first configured to generate the negative voltage and then configured to generate the positive voltage.The device is also equipped with a built-in power stage driver consisting of a pre-driver, driver, and post-driver. The pre-driver is controlled by the oscillator and operates as a power amplifier. The driver is used to drive the N-MOS and P-MOS switches that control the two buck converters, while the post-driver is used to drive the external PWM pin.The operation of the AP7315D-285W5-7 regulator can be modulated by the feedback signals from the output voltages. The output voltage remains constant regardless of the source voltage variations and load conditions. The offset voltage, ripple voltage and output noise are minimized due to the adaptive control scheme and the low-noise switching architecture. The device also features an Enable-pin which enables the integrated oscillator and input under-voltage protection.Conclusion AP7315D-285W5-7 is a linear voltage regulator belonging to the PMIC - Voltage Regulators - Linear category. It is a two-phase, two-output voltage regulator with built in oscillator, enabling smooth circuit startup and dynamic frequency control to reduce EMI. It is suitable for applications with high power requirements, and can be used in applications such as high frequency digital portable electronics, set-top boxes, gaming consoles and other portable products that require both low noise and a compact form factor.
