TPS40211
4.5-V to 52-V wide input range current mode boost controller with 260-mV reference voltage
TPS40211
- Functional Safety-Capable
- Documentation available to aid functional safety system design
- For boost, flyback, SEPIC, LED drive apps
- Wide input operating voltage: 4.5 V to 52 V
- 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)
- Low current disable function
- Create a custom design using the TPS4021x with the WEBENCH Power Designer
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 — 8V to 18V Input, 20V to 35V Output, 700-mA Non-Synchronous Boost Current Regulator for LED Drive
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. (...)
