TPS40211

宽输入范围电流模式升压控制器

The TPS40210 and are wide-input voltage 4.5 V to 52 V, nonsynchronous boost controllers. They are suitable for topologies which require a grounded source N-channel FET including boost, flyback, SEPIC and various LED Driver applications. The device features include programmable soft-start, overcurrent protection with automatic retry and programmable oscillator frequency. Current mode control provides improved transient response and simplified loop compensation. The main difference between the two parts is the reference voltage to which the error amplifier regulates the FB pin.
