Description

The TPS5420D is a High-output-current PWM Converter 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 TPS5420 feedback loop is internally compensated.
Up to 2A continuous (3A 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
Fixed 500kHz switching frequency for small filter size
Improved line regulation and transient response by input voltage feed forward
System protected by overcurrent limiting, over voltage protection and thermal shutdown
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
