Its small size combined with complete functionality makes the device both versatile and easy to use. The controller uses a low-value current-sensing resistor in series with the input voltage and the source connection of the power FET to detect switching current. When the voltage drop across this resistor exceeds 100 mV, the device enters a hiccup fault mode at approximately 2% of the operating frequency. The device uses voltage feedback to an error amplifier that is biased by a precision 700-mV reference. Feed- forward compensation from the input keeps the PWM gain constant over the full input voltage range, eliminating the need to change frequency compensation for different input voltages. The device also incorporates a soft-start feature, where the output follows a slowly rising soft-start voltage, preventing output-voltage overshoot. 7.2 Functional Block Diagram NOTE In this block diagram and the following sections, the internal R resistor values and capacitor mV reference values are typical. Resistor and reference voltage values will vary based on process, temperature, and supply voltage of the device. Please see Electrical Characteristics for tolerances, where applicable. 10 Submit Documentation Feedback Copyright © 2006–2016, Texas Instruments Incorporated Product Folder Links: TPS40200-Q1 |
