LMR33620AP-Q1中文资料3.8V 至 36V、2A 同步降压转换器数据手册TI规格书

描述 Description

The LMR336x0AP-Q1 automotive-qualified regulator is an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class efficiency for rugged applications. The LMR336x0AP-Q1 drives up to 2 A or 3 A of load current from an input of up to 36 V. The LMR336x0AP-Q1 provides high light load efficiency and output accuracy in a very small solution size. Features such as a power-good flag and precision enable provide both flexible and easy-to-use solutions for a wide range of applications. The LMR336x0AP-Q1 automatically folds back frequency at light load to improve efficiency. Integration eliminates most external components and provides a pinout designed for simple PCB layout. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limit, and hiccup short-circuit protection. The LMR336x0AP-Q1 is available in a 12-pin 3-mm × 2-mm next generation VQFN package with wettable flanks.
