Our new auto switching PFM control

circuit automatically switches the duty

ratio according to the load. This

improves the efficiency and reduces

output voltage ripple over a wide

range of load impedances. In other

PFM DC-DC converters, pulses are

skipped at low output currents,

increasing ripple voltage. A built-in

protection circuit prevents damage to

the IC by turning off the MOS FET

when the voltage at the Control pin

exceeds the limit.
