Product Overview

The LTC3604EUD#PBF is a high-efficiency monolithic synchronous Buck Regulator using a phase-lockable controlled on-time and current-mode architecture capable of supplying up to 2.5A of output current. The operating supply voltage range is from 3.6 to 15V, making it suitable for a wide range of power supply applications. The operating frequency is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors. For switching noise sensitive applications, the LTC3604 can be externally synchronized over the same frequency range. An internal phase-locked loop aligns the on-time of the top power MOSFET to the internal or external clock. This unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response.
  • External frequency synchronization
  • Current-mode operation for excellent line and load transient response
  • User selectable low ripple (20mVP-P typical)
  • Short-circuit protection
  • Output voltage tracking capability
  • Power good status output
  • Up to 95% efficiency
  • 5% at 2.25MHz Very low duty cycle operation
  • 0.6V Reference allows low output voltage
