Texas Instruments TPS5410D TPS5410D DC-DC Switching Buck (Step Down) Regulator Adjustable 5.5V-36Vin 1.22V-31Vout 1Aout SOIC-8

The TPS5410D is a 1A 500kHz Step-down Converter that integrates a low-resistance, high-side, N-channel MOSFET. Included on the substrate with the listed features is a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions, an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 5.5V, an internally set slow-start circuit to limit inrush currents and a voltage feed-forward circuit to improve the transient response. Using the ENA pin, shutdown supply current is reduced to 18µA typically. Other features include an active high enable, over-current limiting, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5410 feedback loop is internally compensated.

• Up to 1A continuous (1.2A peak) output current
• High efficiency up to 95% enabled by 110mR integrated MOSFET switch
• Wide output voltage range (adjustable down to 1.22V with 1.5% initial accuracy)
• Internal compensation minimizes external parts count
• Improved line regulation and transient response by input voltage feed-forward
• System protected by over-current limiting, overvoltage protection and thermal shutdown
• Green product and no Sb/Br

Applications

Consumer Electronics, Multimedia, Industrial, Audio, Automotive, Power Management
