AN2063
Application note
VIPower™: low consumption standby power
with the VIPerx2A family
Introduction
The new regulation on the power supply standby consumption for the battery charger is
more and more stringent. Thanks to the VIPerx2A family low power consumption, a battery
charger can be built in standby mode with no-load of 100 mW. This charger solution with the
VIPer12A-E is presented in Table 1.
Some general features:
• Ultra low standby power dissipation
• Burst mode operation in standby
• 72% typical efficiency
• Current mode controller
• Output short-circuit protection
• Thermal shutdown protection
