FP6169
1.5MHz, 2A Synchronous Step-Down Regulator
General Description
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.
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)
Applications
Cellular Telephone
Wireless and DSL Modems
