FP6168 Dual 1.5MHz, 1A Synchronous Step-Down Regulator |
|
General Description |
|
Download |
The FP6168 is a high efficiency current mode dual 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 FP6168 is packaged in DFN-10L to reduce PCB space. .
