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

PublishTime：2021-07-01

The FAN2103 Tiny Buck is an easy-to-use, cost-and space-efficient, 3 A 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 feed forward.
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 plus power-good,help protect the devices from damage during fault conditions.
