Keywords:TPS40210  power converters  oscillator 

With their wide input voltage range, the TPS40210 and TPS40211 PWM controllers are targeted for isolated and non-isolated power converters used in industrial, automotive, and battery-powered applications. The freedom in selecting the power stage and its compensation—as well as the features, such as programmable soft start, adjustable/synchronisable oscillator frequency and internal slope compensation—supports the use of the devices in many applications, says Texas Instruments. The basic converter architecture can provide different power levels by changing the power stage. While the TPS40210 is designed for general purpose applications, the TPS40211 is tailored for driving high-brightness LEDs.
