Texas Instruments  LM46002PWPT

The LM46002 SIMPLE SWITCHER® regulatoris an easy to use synchronous step-down DC-DC converter capable of driving up to 2 A of loadcurrent from an input voltage ranging from 3.5 V to 60 V. The LM46002 provides exceptionalefficiency, output accuracy and drop-out voltage in a very small solution size. An extended familyis available in various load current options and 36 V maximum input voltage in pin-to-pincompatible packages, including LM46001, LM46000, LM43603, LM43602, LM43601 and LM43600. Peakcurrent mode control is employed to achieve simple control loop compensation and cycle-by-cyclecurrent limiting. Optional features such as programmable switching frequency, synchronization,power-good flag, precision enable, internal soft-start, extendable soft-start, and tracking providea flexible and easy to use platform for a wide range of applications. Discontinuous conduction andautomatic frequency reduction at light loads improve light load efficiency. The family requires fewexternal components. Pin arrangement allows simple, optimum PCB layout. Protection features includethermal shutdown, VCC under-voltage lockout, cycle-by-cycle current limit,and output short circuit protection. The LM46002 device is available in the HTSSOP / PWP 16 leadedpackage (5.1 mm x 6.6 mm x 1.2 mm) with 0.65 mm lead pitch.
