Product Overview

The LT3506EDHD#PBF is a dual current mode PWM step-down DC/DC converter with internal 2A power switches. Both converters are synchronized to a single oscillator and run with opposite phases, reducing input ripple current. The output voltages are set with external resistor dividers and each regulator has independent shutdown and soft-start circuits. Each regulator generates a power-good signal when its output is in regulation, easing power supply sequencing and interfacing with microcontrollers and DSPs. The LT3506 switching frequency is 575kHz and the LT3506A is 1.1MHz. These high switching frequencies allow the use of tiny inductors and capacitors, resulting in a very small dual 1.6A output solution. Constant frequency and ceramic capacitors combine to produce low, predictable output ripple voltage. Current mode PWM architecture provides fast transient response with simple compensation components and cycle-by-cycle current limiting.
  • Anti-phase switching reduces ripple
  • Independent shutdown/soft-start pins
  • Independent power good indicators ease supply sequencing
  • Uses small inductors and ceramic capacitors
