Product Overview

The LM46000QPWPTQ1 is a SIMPLE SWITCHER® easy-to-use synchronous step-down DC-to-DC Converter capable of driving up to 500mA of load current from an input voltage range of 3.5 to 60V. The LM46000-Q1 provides exceptional efficiency, output accuracy and drop-out voltage in a very small solution size. 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 and cycle-by-cycle current limit.
  • High efficiency at light load (DCM and PFM)
  • Integrated synchronous rectification
  • Frequency synchronization to external clock
  • Internal compensation
  • Stable with almost any combination of ceramic, polymer, tantalum and aluminium capacitors
  • Power-good flag
  • Soft-start into pre-biased load
  • Extendable soft-start time by external capacitor
  • Output voltage tracking capability
  • Precision enable to program system UVLO
  • Output short-circuit protection with hiccup mode
  • 24µA Quiescent current in regulation
  • 4.1ms Internal soft-start
  • Green product and no Sb/Br
