LTC3565EDD#PBF

LTC3565 is a constant frequency, synchronous step-down DC/DC converter. Intended for medium power applications. The output voltage is adjustable from 0.6V to 5.5V. Internal synchronous power switches provide high efficiency. This device’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. It 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. It is widely used in application such as notebook computers, digital cameras, cellular phones, handheld instruments, board mounted power supplies etc.
