FP6160
1.5MHz, 800mA Synchronous Step-Down
Regulator
General Description
The FP6160 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 FP6160 is packaged in SOT23-5L, and TSOT23-5L to reduce PCB space.
Features
Input Voltage Range: 2.5 to 5.5V Precision Feedback Reference Voltage: 0.6V (±2%) Output Current: 0.8A (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: SOT23-5L, TSOT23-5L
Applications
Cellular Phones Wireless and DSL Modems Digital Still Cameras Portable Products MP3 Players
