Product Overview

The LT3508EUF#PBF is a dual current mode PWM step-down DC/DC Converter with internal power switches capable of generating two 1.4A outputs. The wide input voltage range of 3.7 to 36V makes the LT3508 suitable for regulating power from a wide variety of sources, including automotive batteries, 24V industrial supplies and unregulated wall adapters. Both converters are synchronized to a single oscillator programmable up to 2.5MHz and run with opposite phases, reducing input ripple current. Its high operating frequency allows the use of small inductors and ceramic capacitors, resulting in low, predictable output ripple. Each regulator has independent tracking 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.
  • Synchronizable over the full frequency range
  • Anti-phase switching reduces ripple
  • Uses small inductors and ceramic capacitors
  • Accurate programmable undervoltage lockout
  • Independent tracking, soft-start and power good circuits ease supply sequencing
  • Output adjustable down to 800mV
