摘要： PROBLEM TO BE SOLVED: To dynamically adjust the amount of additional currents to be supplied to a triac dimmer through a triac dimmer controller for an LED lamp on the basis of a triac dimmer operation mode.SOLUTION: A current controller of a triac dimmer continuously detects a triac dimmer current load and determines a triac dimmer operation mode on the basis of a detected current. The triac dimmer controller compares the detected current with a threshold current value called triac hold current and adjusts the amount of voltage divider currents on the basis of a difference between the detected current and the threshold current value. By continuously detecting the triac dimmer current load, an LED controller uses a single sync current path to adjust the amount of voltage divider currents to be supplied to the triac dimmer, thereby satisfying triac dimmer current demands of a plurality of triac dimmer operation modes.

摘要： A replica circuit (115) for a buck converter senses a replica of the current through the low-side switch transistor MLS without using a sense resistor. The replica circuit includes a replica transistor (MREP1, MREP2) and a current sense amplifier CSA, which drives the replica transistor with a first replica current, which is a scaled version of the current through the low-side switch transistor MLS, and generates a second replica current. A resistor (305) converts the second replica current into an output voltage (CSAOUT). A sample switch error amplifier integrator circuit (351) including a sample switch (S1) and an error amplifier (EA) samples the second replica current during a sampling window to generate an error signal (VERR). A controller controls the high-side and low-side switch transistors (MLS, MHS) responsive to the error signal.
