The LTC3539EDCB-2#PBF with Switching Voltage Regulators LTC3539/LTC3539-2 is a high-performance, high-efficiency, synchronous step-up DC/DC converter designed and manufactured by Analog Devices. It is a 2A, 1MHz/2MHz synchronous step-up DC/DC converter with an integrated high-side switch and comes in a 8-Lead 3mm × 3mm DFN package. It operates from an input voltage of 2.7V-6V and delivers an output voltage up to 12V. The efficiency of the device is over 90% and it offers excellent transient performance and integrated fault protection. It also has integrated soft start and voltage tracking, wide operating input/load range, and over-temperature protection. The LTC3539EDCB-2#PBF is ideal for powering processors, DSPs, FPGAs, and ASICs.
