LM46000PWPR Datasheet PDF - TI

●The LM46000 SIMPLE SWITCHER® regulator is an easy to use synchronous step-down DC-DC converter capable of driving up to 500 mA of load current from an input voltage range of 3.5 V to 60 V. The LM46000 provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. An extended family is available in 1 A and 2 A load current options in pin-to-pin compatible packages. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, extendable soft-start, and tracking provide a flexible and easy to use platform for a wide range of applications. Discontinuous conduction and automatic frequency modulation at light loads improve light load efficiency. The family requires few external components and pin arrangement allows simple, optimum PCB layout. Protection features include thermal shutdown, VCC under-voltage lockout, cycle-by-cycle current limit, and output short circuit protection. The LM46000 device is available in the HTSSOP / PWP 16 leaded package (5.1 mm x 6.6 mm x 1.2 mm) with 0.65 mm lead pitch. Pin-to-pin compatible with LM46001, LM46002, LM43603, LM43602, LM43601, and LM43600.
