This part is covered in Fairchild's TinyCalc Calculator™ for the design of TinyBuck™-based regulators.

The FAN2108 TinyBuck™ is a highly efficient, small footprint, 8A, synchronous buck regulator.

The FAN2108 contains both synchronous32 MOSFETs and a controller/driver with optimized interconnects in one package, which enables designers to solve highcurrent requirements in a small area with minimal external components.

External compensation, programmable switching frequency, and current limit features allow design optimization and flexibility.

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.

Fairchild’s advanced BiCMOS power process, combined with low-R_DS(ON) internal MOSFETs and a thermally efficient MLP package, provide the ability to dissipate high power in a small package.

Output over-voltage, under-voltage, and thermal shutdown protections help protect the device from damage during fault conditions. FAN2108 prevents prebiased output discharge during startup in point-of-load applications.
