PAM2325
FAST TRANSIENT 3.5A STEP-DOWN CONVERTER
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.
