Beschreibung

The PAM2321 is a 2A step-down converter with a typical input voltage of 3.3V and a fixed output voltage of1.2V or an adjustable output. The 3MHz switching frequency enables the use of small external components.The ultra-small 3mm x 3mm footprint and high efficiency make the PAM2321 an ideal choice for portableapplications.The PAM2321 delivers 2A maximum output current while consuming only 55μA no-load quiescent current.Low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the PAM2321 the ideal choice forhigh output voltage, high current applications which require a low dropout threshold.The PAM2321 provides excellent transient response and output accuracy across the operating range.The PAM2321 maintains high efficiency throughout the load range. The PAM2321 automatically optimizesefficiency during light load mode (PSM) and maintains constant frequency and low output ripple duringPWM mode.Over-temperature and short circuit protection safeguard the PAM2321 and system components fromdamage.The PAM2321 is available in a Pb-free, ultra-small, low profile, TDFN 3X3-10 and DFN 3X3-6 package. Theproduct is rated over a temperature range of -40°C to +85°C.
