10 A
integrated
Wide Output Voltage Range: 0.8 V to 80% VIN
10 A Output Current
synchronous Buck regulator.
The FAN2110 contains both synchronous MOSFETs
and a controller/driver with optimized interconnects in
one package, which enables designers to solve high-
current requirements in a small area with minimal
external components. Integration helps to minimize
critical inductances making component layout simpler
and more efficient compared to discrete solutions.
1% Reference Accuracy Over Temperature
Over 93% Peak Efficiency
Programmable Frequency Operation: 200 KHz to
600 KHz
.
Fully Synchronous Operation with Integrated
Schottky Diode on Low-Side MOSFET Boosts
Efficiency
The FAN2110 provides for external loop compensation,
programmable switching frequency, and current limit.
These features allow design flexibility and optimization.
High frequency operation allows for all ceramic solutions.

Internal Bootstrap Diode
Power-Good Signal
The summing current mode modulator uses lossless
current sensing for current feedback and over-current
protection. Voltage feedforward helps operation over a
wide input voltage range.
Starts up on Pre-Bias Outputs
Accepts Ceramic Capacitors on Output
External Compensation for Flexible Design
Programmable Current Limit
Fairchild’s advanced BiCMOS power process, combined
with low-RDS(ON) internal MOSFETs and a thermally
efficient MLP package, provide the ability to dissipate
high power in a small package.
Under-Voltage, Over-Voltage, and Thermal
Shutdown Protections
.
.
Internal Soft-Start
Output over-voltage, under-voltage, and thermal
shutdown protections help protect the device from
damage during fault conditions. FAN2110 also prevents
pre-biased output discharge during startup in point-of-
load applications.
