® RT8070 4A, 2MHz, Synchronous Step-Down Converter General Description Features The RT8070 is a simple, easy-to-use current mode controlled 4A synchronous step-down DC-DC converter with an input supply voltage range from 2.7V to 5.5V. The device built-in an accurate 0.8V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high  efficiency in both WDFN-8L 3x3 and SOP-8 (Exposed Pad) packages.  The RT8070 operates in automatic PSM that maintains high efficiency during light load operation. The device features cycle-by-cycle current-limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation. Adjustable softstart function prevents inrush current during start-up. The device also features input under-voltage lockout, output under-voltage protection, and over-temperature protection to provide safe and smooth operation in all operating conditions.            RT8070 Package Type SP : SOP-8 (Exposed Pad-Option 1) QW : WDFN-8L 3x3 (W-Type) Lead Plating System Z : ECO (Ecological Element with Halogen Free and Pb free) 100% Duty Cycle for Lowest Dropout Power Saving Mode for Light Loads Adjustable Frequency : 200kHz to 2MHz 0.8V Reference Allows Low Output Voltage Enable Function External Soft-Start Power Good Function Input Under-Voltage Lockout Protection Output Under-Voltage Protection Over-Temperature Protection RoHS Compliant and Halogen Free Applications    Ordering Information Input Voltage Range from 2.7V to 5.5V Ω FETs Integrated 110mΩ Ω and 70mΩ   LCD TVs and Monitors Notebook Computers Distributed Power Systems IP Phones Digital Cameras Marking Information RT8070ZSP RT8070ZSP : Product Number RT8070 ZSPYMDNN YMDNN : Date Code Note : Richtek products are :  RoHS compliant and compatible with the current require- RT8070ZQW ments of IPC/JEDEC J-STD-020.  Suitable for use in SnPb or Pb-free soldering processes.
