Prezentare generală a produsului

The ADP1850ACPZ-R7 is a dual-phase DC to DC Synchronous Buck Controller capable of running from commonly used 3.3 to 12V (up to 20V) voltage inputs. The device operates in current-mode for improved transient response and uses valley current sensing for enhanced noise immunity. The architecture enables accurate current sharing between interleaved phases for high current outputs. It is ideal in system applications requiring multiple output voltages. It includes a synchronization feature to eliminate beat frequencies between switching devices; provides accurate tracking capability between supplies and includes precision enable for simple, robust sequencing.
  • Integrated boost diodes
  • Power saving mode (PSM) at light loads
  • Accurate power good with internal pull-up resistor
  • Accurate voltage tracking capability
  • Independent channel precision enable
  • Overvoltage and overcurrent limit protection
  • Externally programmable soft start, slope compensation and current sense gain
  • Synchronization input
  • Thermal overload protection Input undervoltage lockout (UVLO)
  • Accurate current sharing between channels (interleaved)
  • 180° Phase shift between channels for reduced input capacitance
