and I
CM
• Higher efficiency leading to less heat generation
• Reduced printed-circuit board requirements.
APPLICATIONS
• Power management
– DC/DC converters
– Supply line switching
– Battery charger
– LCD backlighting.
• Peripheral drivers
– Driver in low supply voltage applications (e.g. lamps
and LEDs).
– Inductive load driver (e.g. relays,
buzzers
and motors).
