SET-POINT RESOLUTION IMPROVEMENT FOR SWITCH MODE POWER SUPPLIES |
摘要 |
A Digital-to-Analog Converter (DAC) produces an analog reference value from a first reference input. The analog reference value and an output value are used to produce an analog error signal. An Analog-to-Digital Converter (ADC) converts the analog error signal to a digital value. The ADC has higher level of resolution than the DAC. An error encoder adjusts the digital value to produce a digital error value using a second reference input. |
