DESCRIPTION MB39A125/126 IS A DC/DC CONVERTER IC FOR CHARGING LI-ION BATTERY, WHICH IS SUITABLE FOR DOWN-CONVERSION, AND USES PULSE WIDTH MODULATION (PWM) FOR CONTROLLING THE OUTPUT VOLTAGE AND CURRENT INDEPENDENTLY. THIS IC INTEGRATES THE BUILD-IN COMPARATOR FOR THE VOLTAGE DETECTION OF THE AC ADAPTER, AND SELECTS THE AC ADAPTER OR BATTERY AUTOMATICALLY FOR POWER SUPPLY TO THE SYSTEM. PROVIDES A WIDE RANGE OF POWER SUPPLY VOLTAGE, LOW STANDBY CURRENT, AND HIGH EFFICIENCY, WHICH MAKES THEM IDEAL AS A BUILT-IN CHARGING DEVICE IN PRODUCTS SUCH AS NOTEBOOK PC. FEATURES: - HIGH EFFICIENCY: 97% (MAX) - BUILT-IN TWO CONSTANT CURRENT CONTROL CIRCUITS - ANALOG CONTROL OF THE CHARGING CURRENT VALUE ( INE1, INE2 TERMINAL) - BUILT-IN AC ADAPTER VOLTAGE DETECTION (ACOK, XACOK TERMINAL) SOCKET: SSOP24   MB39A126 CI 39A126 DC/DC CONVERTER CHARGER SSOP24 TAGS DE MB39A126: 39A126, MB39A126, COMPONENTES ELETRONICOS, MAXIM, CHIP DE CARGA, CI DE CARGA, CI DETECTOR DE AC, CI CONTROLADOR DE CARGA
