Description

The PAM2316 is a 2A step-down sync converter. The 2.5MHz switching frequency enables the use of small external components. The ultra-small 2mm x 2mm footprint and high efficiency make the PAM2316 an ideal choice for portable applications. The PAM2316 delivers A maximum output current while consuming only 55μA no load quiescent current. Low RDS(ON) integrated MOSFETs and 100 duty cycle operation make the PAM2316 the ideal choice for high output voltage, high current applications which require a low dropout threshold. The PAM2316 provides excellent transient response and output accuracy across the operating range. The PAM2316 maintains high efficiency throughout the load range. The PAM2316 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 PAM2316 and system components from damage. The PAM2316 is available in a Pb-free, ultrasmall, low profile, 8-pin 2mmx2mm TDFN package. The product is rated over a temperature range of -40°C to +85°C.
