Product Overview

The LTC3545EUD-1#PBF is a triple high efficiency monolithic synchronous Buck Regulator using a constant frequency, current mode architecture. The regulators operate independently with separate run pins. The 2.25 to 5.5V input voltage range makes it well suited for single Li-ion battery-powered applications. Low ripple pulse skip mode or high efficiency Burst Mode operation is externally selectable. PWM pulse skip mode operation provides very low output ripple voltage while Burst Mode operation increases efficiency at low output loads. Switching frequency is internally set to 2.25MHz or the switching frequency can be synchronized to an external 1 to 3MHz clock. Power good indicators easily allow power on sequencing between the three regulators. The internal synchronous switches increase efficiency and eliminate external Schottky diodes. Low output voltages are supported with the 0.6V feedback reference voltage.
  • Up to 95% high efficiency
  • Power good indicators ease supply sequencing
  • Current mode operation/excellent transient response
