LM46002QPWPRQ1 Datasheet PDF - TI

The LM46002-Q1 SIMPLE SWITCHER® regulator is an easy to use synchronous step-down DC-DC converter capable of driving up to 2 A of load current from an input voltage ranging from 3.5 V to 60 V. The LM46002-Q1 provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. An extended family is available in various load current options and 36 V maximum input voltage in pin-to-pin compatible packages, including LM46001, LM46000, LM43603, LM43602, LM43601 and LM43600. 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 reduction at light loads improve light load efficiency. The family requires few external components. 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 LM46002-Q1 device is available in the HTSSOP / PWP 16 leaded package (5.1 mm × 6.6 mm × 1.2 mm) with 0.65 mm lead pitch.
