The TPS40210-Q1 and TPS40211-Q1 devices are wide-input-voltage (4.5 V to 52 V) non-synchronous boost controllers. They are suitable for topologies that require a grounded source N-channel FET, including boost, flyback, SEPIC, and various LED driver applications. 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.

TPS40210EVM — Development Boards/EVMs

The TPS40210EVM evaluation module (EVM) is a fixed frequency (600kHz) non-synchronous boost converter providing fixed 24.0-V output at up to 2A from a 12V input bus. The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the (...)
