FAN2103 — TinyBuck 3A, 24V Input Integrated Synchronous Buck Regulator December 2007 FAN2103 — TinyBuck 3A, 24V Input Integrated Synchronous Buck Regulator Features Over 95% efficiency Internal power MOSFETs: High-side RDS(ON) = 31mΩ Low-side RDS(ON) = 23mΩ Integrated low-side Schottky diode Programmable frequency operation up to 750KHz Power-good signal Wide input range: 3.0V to 24V Output voltage range: 0.8V to 90%VIN Input under-voltage lockout (UVLO) Programmable over-current protection Under-voltage, over-voltage, and thermal protection Selectable light-load power-saving mode 5x6mm, 25-pin, 3-pad MLP Description The FAN2103 TinyBuck is an easy-to-use, cost- and space-efficient, synchronous buck solution. It enables designers to solve high-current requirements in a small area with minimal external components. External programming of clock frequency, current limit, and loop response allows for optimization and flexibility selecting output filter components and transient response. 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 a thermally efficient MLP package, provides low-RDS(ON), internal MOSFETs, and the ability to dissipate high power in a small package. Under-voltage, thermal shutdown, and power-good are blanked at start-up, but protect the device from damage during fault conditions. Applications Thin ……
