- Adjustable oscillator frequency
- Fixed frequency current mode control
- Internal slope compensation
- Integrated low-side driver
- Programmable closed-loop soft start
- Overcurrent protection
- External synchronization capable
- Reference 700 mV (TPS40210), 260 mV (TPS40211)

The TPS40210 and TPS40211 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.

TPS40211EVM-352 — Regulador de corriente de impulso no síncrono de 700 mA, entrada de 8 V a 18 V, salida de 20 V a 35
The TPS40211EVM-352 evaluation module (EVM) is a fixed frequency, (300 kHz), non-synchronous boostconverter providing fixed 700-mA output at 20 V to 35 V from a 8-V to 18-V input source. The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. (...)
