AP3418KTR-G1 Description

Short technical summary and product information.

The Diodes Incorporated AP3418KTR-G1 is a 1.5A, 1.4MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter. It is designed for high efficiency and excellent line and load regulation, making it ideal for portable equipment powered by single Li-ion batteries.

 

Key features include an input voltage range of 2.5V to 5.5V and an adjustable output voltage from 0.6V to VIN. The device integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance. It also incorporates built-in over-current protection, short-circuit protection, thermal shutdown protection, and an under-voltage lockout (UVLO) function, along with a soft-start feature.

 

The AP3418KTR-G1 is housed in a compact SOT-23-5 package, measuring 1.6mm width and 2.92mm length, suitable for surface mount applications. It operates across an industrial temperature range of -40°C to 85°C.
