PAM2325: Inactive Datasheet Archive

Description

The PAM2325 is a 3.5A step-down synchronous converter. The 1.2MHz switching frequency enables the use of small external components. The ultra-small 2mm x 2mm footprint and high efficiency make the PAM2325 an ideal choice for portable applications. The PAM2325 delivers 3.5A maximum output current while consuming only 55μA no load quiescent current. Low R integrated MOSFETs and 100% duty cycle operation make the PAM2325 the ideal choice for high output voltage, high current applications which require a low dropout threshold. The PAM2325 provides excel lent transient response and output accuracy across the operating range. The PAM2325 maintains high efficiency throughout the load range. The PAM2325 automatically optimizes efficiency during light load mode (PSM) and maintains constant frequency and low output ripple during PWM mode. Over-temperature and short circuit protection safeguard the PAM2325 and system components from damage. The PAM2325 is available in an ultra-small QFN2x2-12 package. The product is rated over a temperature range of -40°C to +85°C.
