All rights reserved. is a registered trademark of Richtek Technology Corporation. © Simplified Application Circuit Ordering Information Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. Applications Distributive Power Systems Battery Charger DSL Modems Pre-regulator for Linear Regulators 3A, 36V, 500kHz Current Mode Asynchronous Step-Down Converter General Description The RT2808A is a current mode asynchronous step-down converter that achieves excellent load and line regulation. Over a wide input voltage range from 5.5V to 36V and supports output current up to 3A. The Current mode operation provides fast transient response and eases loop stabilization. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode, the regulator draws only 25 μA of supply current. The RT2808A requires a minimum number of readily available external components, providing a compact solution. The RT2808A provides protection functions inducing input under voltage lockout, cycle-by-cycle current limit, short circuit protection and thermal shutdown protection. The RT2808A is available in the SOP-8 (Exposed Pad) package. Features 3A Output Current Wide Operating Input Range 5.5V to 36V Adjustable Output Voltage from 1.222V to 26V High Efficiency up to 90% Internal Compensation Minimizes External Parts Count Internal Soft-Start 110m Ω Ω Ω Ω Ω Internal Power MOSFET Switch 25 μμμμμA Shutdown Mode Fixed 500kHz Frequency Thermal Shutdown Cycle-by-Cycle Current Limit Available In an SOP-8 (Exposed Pad) Package RoHS Compliant and Halogen Free Marking Information RT2808AGSP : Product Number YMDNN : Date Code RT2808A GSPYMDNN Package Type SP : SOP-8 (Exposed Pad-Option 2) RT2808A Lead Plating System G : Green (Halogen Free and Pb Free) VIN EN GND BOOT FB SW L R1 R2 VOUT Chip Enable VIN RT2808A D1 CBOOT COUT CIN |
