General Description
EML3170 is a high efficiency current mode synchronous buck PWM DC-DC
regulator.
The internal generated 0.
8V precision feedback
Output Current: 3A (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
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 c...
