The LTC3787 operates from an input voltage ranging from 4.5V to 38V during start-up, maintains operation down to 2.5V after start-up and can regulate an output voltage as high as 60V. The powerful 1.2Ohm onboard N-channel MOSFET gate drivers are capable of slewing large MOSFET gates quickly. The device’s current-mode architecture, clock output and phase modulation enable easy paralleling of multiple devices for up to 12-phase operation. The LTC3787 has a phase-lockable frequency from 75kHz to 850kHz or a selectable fixed frequency from 50kHz to 900kHz.
The LTC3787 is available in SSOP-28 and 4mm x 5mm QFN-28 packages. The 1000-piece price starts at $4.88 each for the H-grade devices and $12.39 each for the MP-grade parts.
