LOW CONSUMPTION VOLTAGE AND CURRENT CONTROLLER FOR BATTERY CHARGERS AND ADAPTORS
- CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROL - LOW CONSUMPTION - LOW VOLTAGE OPERATION - LOW EXTERNAL COMPONENT COUNT - CURRENT SINK OUTPUT STAGE - EASY COMPENSATION - HIGH AC MAINS VOLTAGE REJECTION
VOLTAGE REFERENCE - FIXED OUTPUT VOLTAGE REFERENCE 1.25V - 0.5% AND 1% VOLTAGE PRECISION
DESCRIPTION TSM1012 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) mode. TSM1012 integrates one voltage reference and two operational amplifiers (with ORed outputs - common collectors). The voltage reference combined with one operational amplifier makes it an ideal voltage controller. The other operational, combined with few external resistors and the voltage reference, can be used as a current limiter.
Наличие высокого напряжения на присоске можно проверить отверткой, соединенной с корпусом через резистор 3-5 МОм Наличие резистора обязательно, так как без него из-за большого тока можно повредить умножитель или строчный трансформатор типа ТДКС.
