EML3170-1.5MHz 3A,Synchronous Step-Down Regulator DataSheet
General Description
EML3170 is a high efficiency current mode synchronous buck PWM DC-DC regulator. The internal generated 0.8V 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.
