6 A Output Current
Wide Input Range: 3 V - 24 V
Output Voltage Range: 0.8 V to 80% VIN
Over 95% Peak Efficiency
The FAN2106 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
Programmable Frequency Operation: 200 KHz to
600 KHz
.
Fully Synchronous Operation with Integrated
Schottky Diode on Low-Side MOSFET Boosts
Efficiency
The
FAN2106
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
Internal Soft-Start
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 on Pre-Biased 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
Protections
.
5x6 mm, 25-Pin, 3-Pad MLP Package
Output over-voltage, under-voltage, over-current, and
thermal shutdown protections help protect the device
from damage during fault conditions. FAN2106
prevents pre-biased output discharge during startup in
point-of-load applications.
