® RT8297A/B 1.5A, 17V, 340/800kHz Synchronous Step-Down Converter General Description Features The RT8297A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 1.5A output current from a 4V to 17V input supply. The RT8297A/B's current mode architecture allows the transient response to be optimized. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault conditions also include output under voltage protection, output over voltage protection, and thermal shutdown. The low current (<5μA) shutdown mode provides output disconnect, enabling easy power management in battery-powered systems. The RT8297A/B is available in a WDFN-8L 2x2 package.  4V to 17V Input Voltage Range  1.5A Output Current Internal N-MOSFETs Current Mode Control Fixed Frequency Operation : 340kHz/800kHz Output Adjustable from 0.8V to 12V Up to 95% Efficiency Internal Compensation Stable with Low ESR Ceramic Output Capacitors Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout Output Under Voltage Protection Output Over Voltage Protection Power Good Indicator Thermal Shutdown Protection RoHS Compliant and Halogen Free             Ordering Information  RT8297A/B  Lead Plating System Z : ECO (Ecological Element with Halogen Free and Pb free) A : 340kHz B : 800kHz Note : Richtek products are :  RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.  Applications      Industrial and Commercial Low Power Systems Computer Peripherals LCD Monitors and TVs Green Electronics/Appliances Point of Load Regulation for High-Performance DSPs, FPGAs, and ASICs Pin Configuration (TOP VIEW) Suitable for use in SnPb or Pb-free soldering processes.
