open-in-new Find other Boost controllers (external switch)


The TPS40210-EP is a wide-input voltage (4.5 to 52 V), nonsynchronous boost controller. The device is 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.

document-generic User guide
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 (...)
