The LTC3784 operates from an input voltage range of 4.5V to 60V during start-up, but can maintain operation down to 2.3V after start-up, while regulating an output voltage as high as 60V. This device can produce a 24V output at 10A from a 12V input with 97% efficiency. When configured for Burst Mode® operation, the LTC3784’s 28µA quiescent current makes it ideal for “Always-ON” automotive applications to extend battery run-time during standby mode while keeping the output voltage in regulation. The powerful 1.2 Ω onboard N-channel MOSFET gate drivers are capable of slewing large MOSFETs quickly. The device’s current mode architecture, clock output and phase modulation enable easy paralleling of multiple devices for up to 12-phase operation for very high power applications. In keep alive applications where the input voltage may exceed the regulated output voltage, the LTC3784 allows the synchronous MOSFET to be kept on continuously (100% Duty Cycle) so that the output voltage follows the input voltage with minimal power loss. The LTC3784 is available in an SSOP-28 and 4mm x 5mm QFN-28 packages. It is also available in Extended, Industrial, Automotive, and Military temp grades.
