The MP4415MGQB-P is a part of PMIC - Voltage Regulators - DC DC Switching Regulators. It is a low output voltage, wide input voltage, constant current, 3 step, non-synchronous buck converter. It is specially designed for applications such as LED drivers, industrial and battery powered applications, AC/DC adapter or other regulated voltage or current applications.The MP4415MGQB-P works based on pulse-width modulation (PWM) control schemes. The output current is regulated via a fractional VOUT. The input voltage is centered around VOUT with a voltage divider and the feedback voltage error amplifies it. The high rate pulse-width modulated current mode control is used to maintain a very low output ripple with a high switching frequency of 450 KHz, usually constituting of less than 10mV.The MP4415MGQB-P features an internal soft start, reducing the inrush current. It also includes an integration of high voltage power switch and a load switch in an 8-pin package to save the board space. Also, the over-current protection, thermal shutdown, and short-circuit protection are provided to guarantee the safe surge in current.Additionally, the MP4415MGQB-P incorporates frequency transmission switching architecture, leading to improved efficiency. It works by scanning the input voltage, output voltage and output current pulses, reinstating the pulses available at the output, based on the frequency compensation set in the load feed-back loop. This helps the regulator to perform at higher efficiency levels, up to 94%. The wide input voltage and output current range further help maintain the optimal efficiency for the applications and making it ideal for battery powered and frequently connected applications.Moreover, the MP4415MGQB-P is suitable for a wide range of applications such as charger, DC/DC power supplies, personal audio, mobile device, set-top box and so on. The constant current control mode of this regulator can provide as long as 0.2A output current, enabling it to work as an ideal current supply for LED drivers, industrial and battery-powered applications. This makes it even more useful in the modern power management market.Finally, the MP4415MGQB-P is a highly versatile and efficient, 3-step, non-synchronous buck converter suited for a wide range of applications, with a high switching frequency of 450 KHz, constant current control, over-current protection, thermal shutdown protection and short-circuit protection. Its low output ripple, wide input voltage and output current range, and small 8-pin package make it an ideal choice for applications such as LED drivers, industrial and battery powered applications, AC/DC adapter, as well as other regulated voltage and current applications.
