Texas Instruments TPS54334DDA TPS54334DDA DC-DC Switching Buck Step Down Regulator Adjustable 4.2V-28Vin 800mV-24Vout 3Aout HSOP-8
Texas Instruments TPS54334DDA TPS54334DDA DC-DC Switching Buck Step Down Regulator Adjustable 4.2V-28Vin 800mV-24Vout 3Aout HSOP-8
The TPS54334DDA is a synchronous monolithic Buck Converter with integrated MOSFETs. The TPS54334 enables small designs by integrating the MOSFETs and implementing current mode control to reduce external component count. Efficiency is maximized through the integrated 128/84mR MOSFETs, low quiescent supply current and pulse skipping at light loads. Using the enable pin, shutdown supply current is reduced to 2ĆĀµA by entering a shutdown mode. The TPS54334 provides accurate regulation for a variety of loads with an accurate 1.5% voltage reference over temperature. Cycle-by-cycle current limiting on the high-side FET protects the TPS54334 in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection will be triggered if the overcurrent condition has persisted for longer than the preset time.
- Power good function
- Fixed-frequency current mode control
- Pulse skipping boosts efficiency at light loads
- Overcurrent protection for both MOSFETs with hiccup mode for severe fault conditions
- Thermal and overvoltage transient protection
- Monotonic start-up into pre-biased outputs
- 0.8V Internal voltage reference with ĆĀ±1.5% accuracy over temperature
- Green product and no Sb/Br
