FAN2103 — TinyBuck 3A, 24V Input, Integrated Synchronous Buck Regulator May 2008 FAN2103 — TinyBuck 3A, 24V Input, Integrated Synchronous Buck Regulator Features 3A Output Current Over 95% Efficiency Fully Synchronous Operation with Integrated Schottky Diode on Low-side MOSFET Boosts Efficiency Programmable Frequency Operation (200KHz to 600KHz) Power-good Signal Accepts Ceramic Capacitors on Output External Compensation for Flexible Design Wide Input Range: 3V to 24V Output Voltage Range: 0.8V to 90%VIN Input Under-voltage Lockout Programmable Over-current Limit Under-voltage, Over-voltage, and Thermal Protections 5x6mm, 25-pin, 3-pad MLP Description 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 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. Related Ap……
