Description

  • PMP6572.1, 16Vdc-40Vdc input current/power regulated energy storage with high power LED drive. Reference design uses the TPS40210 current mode controller in a SEPIC converter to regulate either the input current or an approximation of input power to charge a high energy storage capacitor bank at 35V. When externally commanded, the stored energy provides power to a 9A current regulated sync buck LED driver for short durations
