LTC3624IDD-25#PBF

LTC3624IDD-25#PBF is a high-efficiency 17V, 2A synchronous monolithic step-down regulator. This regulator features ultralow quiescent current and high efficiency over a wide VOUT range. The step-down regulator operates from an input voltage range of 2.7V to 17V and provides an adjustable output range from 0.6V to VIN while delivering up to 2A of output current. A user-selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency; Burst Mode operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest voltage ripple. The MODE pin can also be used to sync the switching frequency to an external clock. Applications include battery-powered equipment, portable instrumentation, emergency radios, and general-purpose step-down supplies.

• Wide VIN range from 2.7V to 17V, overtemperature protection
• Current mode operation for excellent line and load transient response
• Synchronizable to external clock, internal compensation and soft-start
• Pulse-skipping, forced continuous, Burst Mode® operation
• 2A rated output current, ±1% output voltage accuracy
• Input quiescent current is 0.1µA typical at (shutdown mode, VRUN = 0V, TJ = 25°C)
• Minimum on-time is 60ns typical at (TJ = 25°C)
• Oscillator frequency is 2.25MHz typical at (TJ = 25°C)
• Internal soft-start time is 1ms typical at (TJ = 25°C)
• Operating temperature range from -40°C to 125°C, 8-lead plastic DFN package
