Product Overview

LTC3626 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying upto 2.5A of output current. The operating supply voltage range is 3.6V to 20V, making it suitable for a wide range of power supply applications. The operating frequency is programmable from 500KHz to 3MHz with an external resistor allowing the use of small surface mount inductors. For applications sensitive to switching noise, this device 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 controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response. It is used in application such as distributed power systems, battery-powered instruments, point-of-load power supply etc.
  • Wide output voltage range of 0.6V to 97% VIN optimized for 0.6V to 6V
  • Low RDS(ON) integrated switches provide upto 95% efficiency
  • Upto 2.5A of output current
  • Average input and output current monitoring, programmable average input/output current limit
  • Die temperature monitor and programmable limit, external frequency synchronization
  • Current mode operation for excellent line and load transient response
  • 0.6V reference with 1% accuracy over temperature
  • User selectable Burst Mode® operation or forced continuous operation
  • Short-circuit protected, output voltage tracking capability, power good status output
  • Operating temperature is -40°C to 125°C, package style is 20-lead plastic QFN
