A Product Line of Diodes Incorporated PAM2321 3MHz, FAST TRANSIENT 2A STEP-DOWN CONVERTER Description The PAM2321 is a 2A step-down converter with a typical input voltage of 3.3V and a fixed output voltage of 1.2V or an adjustable output. The 3MHz switching frequency enables the use of small external components. The ultra-small 3mmx3mm footprint and high efficiency make the PAM2321 an ideal choice for portable applications. 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 for high output voltage, high current applications which require a low dropout threshold.
