LTC3568EDD#TRPBF

LTC®3568 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 2mm or less in height. The output voltage is adjustable from 0.8V to 5V. Internal synchronous 0.11ohm power switches with 2.4A peak current ratings provide high efficiency. This current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. For reduced noise and RF interference, the SYNC/MODE pin can be configured to skip pulses or provide forced continuous operation. Application includes notebook computers, digital cameras, cellular phones, handheld instruments, board mounted power supplies.
