FAN2106 — TinyBuck™
6A, 24V Input, Integrated Synchronous Buck Regulator
Features
Description
The FAN2106 TinyBuck™ is an easy-to-use, cost and
space-efficient, 6A synchronous buck solution. It
enables designers to solve high current requirements in
a small area with minimal external components.
6A Output Current
Over 95% Efficiency
Fully Synchronous Operation with Integrated
Schottky Diode on Low-side MOSFET Boosts
Efficiency
External compensation, programmable switching
frequency, and current limit features allow for design
optimization and flexibility.
Programmable Frequency Operation: 200KHz to
600KHz
The summing current mode modulator uses lossless
current sensing for current feedback and over-current,
and includes voltage feedforward.
Power-good Signal
Accepts Ceramic Capacitors on Output
External Compensation for Flexible Design
Wide Input Range: 3V to 24V
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.
Output Voltage Range: 0.8V to 90% VIN
Input Under-voltage Lockout
Output over voltage, under voltage, and thermal
shutdown protections help protect the device from
damage during fault conditions.
Programmable Current Limit
Under-voltage, Over-voltage, and Thermal
Protections
