LT3514 Triple Step-Down Switching
Regulator with 100% Duty Cycle Operation DESCRIPTION
The LT®3514 consists of three buck regulators (2A, 1A, 1A output current). The device has a wide operating input range of 3.2V to 36V. An on-chip boost regulator allows each channel to operate up to 100% duty cycle. The LT3514 is designed to minimize external ponent count and results in a...
