Product Overview

The LT3507AEFE#PBF is a triple Monolithic Step-Down Regulator with internal power switches and a low dropout regulator. The switching converters are step-down converters capable of generating one 2.7A output and two 1.8A outputs. All three converters are synchronized to a single oscillator. The 2.7A output runs with opposite phase to the other two converters, reducing input ripple current. Each regulator has independent shutdown and soft-start circuits and generates a power good signal when its output is in regulation, easing power supply sequencing and interfacing with microcontrollers and DSPs. The switching frequency is set with a single resistor yielding a range of 250kHz to 2.5MHz. The high switching frequency allows the use of small inductors and capacitors resulting in a very small triple output supply. The constant switching frequency, combined with low impedance ceramic capacitors, results in low, predictable output ripple.
  • Low dropout linear regulator with external transistor
  • Antiphase switching reduces ripple
  • Independent run, tracking/soft-start and power good indicators ease supply sequencing
  • Uses small inductors and ceramic capacitors
  • User programmable overvoltage and undervoltage lockouts
