GENERAL DESCRIPTION
The LTC?7897 is a high performance, 100% duty cycle
capable, synchronous step-down, DC/DC switching
regulator controller that drives all N-channel
synchronous silicon metal oxide field effect transistor
(MOSFET) power stages. Synchronous rectification
increases efficiency, reduces power loss, and simplifies
the application design by reducing thermal
requirements.
The wide input and output voltage ranges of the
LTC7897 enable not only high step-down ratios but also
a wide range of positive to negative voltage conversion.
The gate drivers of the LTC7897 provide robustness with
a 15V ABS MAX rating and flexibility with adjustable
drive levels and dead times to optimize applications.
The gate drive voltage of the LTC7897 can optionally be
adjusted from 5V to 10V to allow use of logic-level or
standard threshold MOSFETs. The dead times of the
LTC7897 can be optimized with external resistors for
margin or to tailor the application for higher efficiency
and allow for high frequency operation.
