AN11060 TEA172X 5 W to 11 W Power Supply/USB charger Rev. 1.2 8 June 2012 Application note Document information Info Content Keywords Ultra-low standby power, constant output voltage, constant output current, primary sensing, integrated high-voltage switch, integrated high-voltage start-up, USB charger, standby supply, 5 W to 11 W supply. Abstract The TEA172X are primary sensing controllers for power supplies up to 5 W or 11 W (depending on version) with an integrated high-voltage switch. No-load power is as low as 10 mW (depending on version) and they surpass the Energy Star 5 level requirement (30 mW). When the maximum output power is exceeded, the IC changes from constant voltage mode to constant current mode, which is ideally suited for battery charging.AN11060 NXP Semiconductors TEA172X 5 W to 11 W Power Supply/USB charger Revision history Rev Date Description v.1.2 20120608 third issue v.1.1 20120501 second issue v.1 20120130 first issue Contact information For more information, please visit:
