The TPS40210-Q1 and TPS40211-Q1 devices are wide-input voltage non-sync boost controllers. These devices can be used in various topologies such as boost, flyback, SEPIC, and various LED driver applications because of its grounded source N-channel FET. The device also features programmable soft start, overcurrent protection, and programmable oscillator frequency. Current mode control provides improved transient response and simplified loop compensation. The TPS40210-Q1 and TPS40211-Q1 devices differ in the reference voltage to which the error amplifier regulates the FB pin.
