Description
The FAN5092 is a synchronous multi-slice DC-DC
controller IC which provides a highly accurate,
programmable output voltage for all high-current
applications. Two interleaved synchronous buck regulator
phases with built-in current sharing operate 180
° out of
phase to provide the fast transient response needed to satisfy
high current applications while minimizing external
components. FAN5092s can be paralleled while maintaining
both frequency and phase synchronization and ensuring
current sharing in a high-power system. The FAN5092
features remote voltage sensing, Programmable Active
Droop
and advanced response for optimal converter
transient response with minimum output capacitance. It has
integrated high-current gate drivers with adaptive delay gate
switching, eliminating the need for external drive devices.
These make it possible to create power supplies running at a
switching frequency as high as 4MHz, for ultra-high density.
The output voltage can be set from 1.1V to 5V with an
accuracy of 0.5%. The FAN5092 uses a high level of
integration to deliver load currents in excess of 150A from a
12V source with minimal external circuitry. The FAN5092
also offers integrated functions including Power Good,
Output Enable/Soft Start, under-voltage lockout, over-
voltage protection, and current limiting with independent
current sense on each slice. It is available in a 28-pin TSSOP
package.
