This part is covered in Fairchild's TinyCalc
Calculator™ for the design of TinyBuck™-based regulators.
The FAN2110 TinyBuck™ is a highly efficient, small footprint, constant
frequency, 10A integrated 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.
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.
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-RDS(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. FAN2110 also prevents
pre-biased output discharge during startup in point-of-load applications.
