TPS40211DGQ Datasheet PDF - TI

The TPS40211DGQ is a wide input range current-mode Boost Controller 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.

● Fixed frequency current mode control

● Internal slope compensation

● Integrated low-side driver

● Programmable closed-loop soft-start

● Overcurrent protection

● External synchronization capable

● Low current disable function

● Green product and no Sb/Br
