FP6169 1.5MHz, 2A Synchronous Step-Down Regulator General Description Download 　The FP6169 is a high efficiency current mode synchronous buck PWM DC-DC regulator. The internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low RDS (ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving the current consumption. The FP6169 is packaged in SOP-8L to reduce PCB space. . ˙Data Sheet Features ˙Input Voltage Range: 2.5 to 5.5V ˙Adjustable Output Voltage From 0.6V to VIN ˙Precision Feedback Reference Voltage: 0.6V (±2%) ˙Output Current: 2A (Max.) ˙Duty Cycle: 0~100% ˙Internal Fixed PWM Frequency: 1.5MHz ˙Low Quiescent Current: 100μA ˙No Schottky Diode Required ˙Built-in Soft Start ˙Current Mode Operation ˙Over Temperature Protection ˙Package: SOP-8L (EP)
