Description of LM46001PWPR
The LM46001 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 1 A of load current from an input voltage ranging from 3.5 V to 60 V. The LM46001 provides exceptional efficiency, output accuracy, and dropout voltage in a very small solution size. An extended family is available in 0.5-A and 2-A load current options in pin-to-pin compatible packages. Peakcurrent-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-touse platform for a wide range of applications. Discontinuous conduction and automatic frequency reduction 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 undervoltage lockout, cycle-by-cycle current limit, and output short-circuit protection. The LM46001 device is available in the 16-lead HTSSOP package (PWP, 6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch. The device is pin-to-pin compatible with LM46000, LM46002, LM43603, LM43602, LM43601, and LM43600
