The LTC3899IUHF#PBF is a high-performance triple output DC-DC switching controller manufactured by LT (Linear Technology). This controller drives all N-channel synchronous power MOSFET stages and utilizes a constant frequency current-mode architecture, allowing for a phase-lockable frequency up to 850kHz.
It operates from a wide input supply range of 4.5V to 60V. The device can also operate from an input supply as low as 2.2V after start-up when biased from the output of a boost converter or another auxiliary supply. The gate drive for the controller is programmable from 5V to 10V, enabling the use of logic-level or standard-level FETs to maximize efficiency.
Key electrical specifications include an input voltage range of 4.5V to 60V, an output voltage range of 0.8V to 60V, and a maximum output current of 15A. The switching frequency is 835kHz with a maximum duty cycle of 99%. The operating temperature range is -40°C to 125°C.
The LTC3899IUHF#PBF is supplied in a 38-pin QFN package and is designed for surface mounting. Its compact size, with a height of 0.75mm, makes it suitable for space-constrained applications.
The input voltage range is 4.5V to 60V.
It supports 3 outputs.
The switching frequency is 835 kHz.
The operating temperature range is -40°C to 125°C.
It is in a QFN-38 package.
The RoHS Status is RoHS3 Compliant.
