uP6281
12V MOSFET Drivers with Output Disable
for Single Phase Synchronous-Rectified Buck Converter
General Description
Features
The uP6281 is a dual, high voltage MOSFET driver optimized
for driving two N-Channel MOSFETs in a synchronous-
rectified buck converter. Each driver is capable of driving a
5000pF load with 30ns transition time. This device combined
with uPI multi-phase buck PWM controller forms a complete
core voltage regulator for advanced micro-processors.
The uP6281 features adaptive anti-shoot-through protection
that prevents cross-conduction of the external MOSFET
while maintains minimum deadtime for optimized efficiency.
Both gate drives are turned off by pulling low OD# pin or
high-impedance at PWM pin, preventing rapid output
capacitor discharge during system shutdowns.
Other feature is supply input under voltage lockout. The
uP6281 is available in thermal enhanced PSOP-8L or
WDFN3x3-8L packages.
Applications
† Core Voltage Supplies for Desktop,
Motherboard CPUs
† High Frequency Low Profile DC/DC Converters
† High Current Low Voltage DC/DC Converters
† All-In-One Synchronous Buck Drivers
† Bootstrapped High-Side Driver
† Adaptive Anti-Shoot-Through Protection
Circuitry
† 1 PWM Signal Generates both Drivers
† Tri-State Input for Bridge Shutdown
† Output Disable Control Turns Off both MOSFETs
† Under Voltage Lockout for Supply Input
† PSOP-8L or WDFN3x3-8L Packages
† RoHS Compliant and Halogen Free
