MX8830R
General Description
The MX8830 family are 1A Source / 1A Sink Synchronous Buck
MOSFET Drivers. These Synchronous Buck MOSFET Drivers
are specifically designed to drive two N-channel power
MOSFETs in a synchronous buck converter. The High-Side
driver is powered via a bootstrapped power connection. The
driver is capable of 13ns High-Side output, and 12ns Low-Side
output transition times driving a 3000pF load.
The MX8830B, MX8830R, and MX8830X incorporate an
undervoltage lockout to prevent unintentional gate drive output
during low voltage conditions. The MX8830R/X include External
Shutdown, and the MX8830X Low-Side Drive Shutdown
features. Simultaneous shutdown of both outputs prevents
rapid output capacitor discharge. The high-side turn-on delay
is adjustable with an external capacitor added at the DLY pin.
The MX8830B/MX8830R/MX8830X are designed to operate
over a temperature range of -40°C to +85°C. The MX8830B is
available in an 8-Lead SOIC, and the MX8830R in a 10-lead
DFN.
