MIC45208-2YMP T1

直流-直流开关降压稳压器, 可调, 4.5V-26V输入, 800mV-5.5V输出, 10A输出, QFN-52

The is a synchronous step-down Regulator Module featuring a unique adaptive on-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor and an inductor. Simplifying the design and layout process for the end user. This highly-integrated solution expedites system design and improves product time-to-market. The internal MOSFETs and inductor are optimized to achieve high efficiency at a low output voltage. The fully-optimized design can deliver up to 10A current under a wide input voltage range of 4.5 to 26V, without requiring additional cooling. It uses Hyper Speed Control™ HSC architecture, which enables ultrafast load transient response, allowing for a reduction of output capacitance. It offers 1% output accuracy that can be adjusted from 0.8 to 5.5V with two external resistors. Additional features include thermal shutdown protection, input undervoltage lockout and adjustable current limit.
