SL1707

产品详情

1.5MHz, 2A Synchronous Step-Down Regulator

General Description

      The SL1707 is a high efficiency current mode synchronous buck PWM DC-DC . 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 SL1707(SOT23-5) to reduce PCB space.
