ANALOG DEVICES LT3507EUHF#TRPBF

LT®3507 is a triple, current mode, DC/DC converter with internal power switches and a low dropout regulator. The switching converter is step-down converter capable of generating one 2.4A output and two 1.5A outputs. This regulator has independent shutdown and soft-start circuits, and generates a power good signal when its output is in regulation, easing power supply sequencing and interfacing with microcontrollers and DSPs. The high switching frequency allows the use of small inductors and capacitors resulting in a very small triple output supply. The constant switching frequency, combined with low impedance ceramic capacitors, results in low, predictable output ripple. With its wide input voltage range of 4V to 36V, it regulates a broad array of power sources including 5V logic rails, unregulated wall transformers, lead acid batteries and distributed power supplies. Typical applications are DSL and cable modems, distributed power regulation, DSP power, automotive.
