Description

General part information

LTC3565 Series

The LTC3565 is a constant frequency, synchronous step-down DC/DC converter. Intended for medium power applications, it operates from a 2.5V to 5.5V input voltage range and has a user-configurable operating frequency up to 4MHz, allowing the use of tiny, low cost capacitors and inductors 1mm or less in height. The output voltage is adjustable from 0.6V to 5.5V. Internal synchronous power switches provide high efficiency. The LTC3565’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors.The LTC3565 can be configured for automatic power saving Burst Mode operation (IQ= 40μA) to reduce gate charge losses when the load current drops below the level required for continuous operation. For reduced noise and RF interference, the SYNC/MODE pin can be configured to skip pulses or provide forced continuous operation.To further maximize battery life, the P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, the device draws <1μA.ApplicationsNotebook ComputersDigital CamerasCellular PhonesHandheld InstrumentsBoard Mounted Power Supplies
