HM2675HV
DESCRIPTION
HM2675HV is the monolithic IC designed for a step-down DC/DC converter capable of driving 3A load without an additional transistor. The input voltage range is up to 60V. Its feedback voltage, VFB, is 200m V. The HM2675HV operates at a switching frequency of 52k Hz. The external shutdown function is controlled by a logic level on the ON/OFF pin and then the circuit es into the standby mode with ISTBY~50µA (typ.). The ON/OFF pin may be used for the analog dimming. As the voltage on the ON/OFF pin is increased from 0.07V to 0.67V, the voltage on the FB pin falls from 200m V to 0. The self-protection features include a cycle-by-cycle current limit and a thermal protection. The HM2675HV is available in standard TO-220, TO-263 packages and ESOP8 package (for ILOAD < 3.0A).
