## Description

The LTC3539EDCB-2#TRPBF is a synchronous, 2A step-up DC/DC converter designed for high efficiency in a low-profile package. It operates with a fixed switching frequency of 2MHz, enabling the use of small external components. The converter features a low start-up voltage of 700mV and can operate down to 500mV once started, extending battery life.

Key electrical specifications include a 1.5V to 5.25V output voltage range and a feedback voltage tolerance of ±1.5%. It offers selectable Burst Mode or PWM operation and a low shutdown current of under 1µA. The device is internally compensated, reducing external component count and simplifying design.

The LTC3539EDCB-2#TRPBF is housed in a compact 2mm x 3mm x 0.75mm DFN package, suitable for space-constrained applications. Its applications include medical instruments, portable bar code scanners, noise-canceling headphones, portable GPS navigation, and handheld PCs.
