The PAM2325 is a 3.5A step-down synchronous converter. The switching frequency of 1.2MHz allows the use of small external components. The ultra-small 2mm x 2mm footprint and high efficiency make the PAM2325 ideal for portable applications. The maximum output current is 3.5A, while only 55 μA of no-load stationary current is consumed. The low R integrated mosfet and 100% duty cycle operation make the PAM2325 ideal for high output voltage, high current applications where low step-down thresholds are required.

Functional block diagram
The PAM2325 provides excellent instantaneous response and output accuracy throughout the operating range. The PAM2325 maintains high efficiency throughout the load range. The PAM2325 automatically optimizes efficiency in light load mode (PSM) and maintains constant frequency and low output ripple in PWM mode. Over-mild short-circuit protection to prevent damage to PAM2325 and system components. The PAM2325 is an ultra-small QFN2x2-12 package. The product is rated for temperatures ranging from -40°C to +85°C.
