LTC3413EFETRPBF - Brand New Analog Devices / Linear Technology IC Chips
-
Description
The LTC3413EFETRPBF is a high-efficiency monolithic synchronous step-down DC/DC converter that operates from an input voltage range of 2.25V to 5.5V. It provides a regulated output voltage equal to half of the reference voltage while sourcing or sinking up to 3A of output current. The internal voltage divider eliminates the need for external resistors by dividing the reference voltage in half. The LTC3413EFETRPBF features an internal synchronous power switch with 85mΩ on-resistance, increasing efficiency and eliminating the need for an external Schottky diode. It can be programmed to switch frequencies up to 2MHz with the use of an external resistor.
