FAN2103 − TinyBuck™ - 3A, 24V Input, Integrated Synchronous Buck Regulator

This part is covered in Fairchild's < href="http://www.fairchildsemi.com/design_tools/tinycalc/tinycalc.html">TinyCalc Calculator™ for the design of TinyBuck™-based regulators.The FAN2103 TinyBuck™ is an easy-to-use, cost- and space-efficient, 3A synchronous buck solution. It enables designers to solve high current requirements in a small area with minimal external components.External compensation, programmable switching frequency, and current limit features allow for design optimization and flexibility.The summing current mode modulator uses lossless current sensing for current feedback and over-current, and includes voltage feedforward.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 plus power-good, help protect the devices from damage during fault conditions.
