Product Summary

The TPS40211DGQ is a wide-input voltage (4.5 V to 52 V), non-synchronous boost controllers. The device is suitable for topologies which require agrounded source N-channel FET including boost, flyback, SEPIC and various LED Driver applications. The TPS40211DGQ features include programmable soft start,overcurrent protection with automatic retry and programmable oscillator frequency. Current modecontrol provides improved transient response andsimplified loop compensation. The main difference between the two parts is the reference voltage towhich the error amplifier regulates the FB pin. The applications of the TPS40211DGQ include LED Lighting, Industrial Control Systems; Battery Powered Systems.
