The TPS5430 is a new DC/DC switching power conversion chip from TI (Texas Instruments, USA). Its superior performance has made it a widespread concern when it has just been launched.
A member of SWIFTTM's family of DC/DC regulators, the TPS5430 is a high output current PWM converter that integrates a low impedance, high side N-channel MOSFET. It integrates a high-performance voltage error amplifier with tight voltage regulation accuracy under transient conditions, an undervoltage lockout function to prevent the input voltage from starting at 5,5V, and a built-in slow-start circuit to limit inrush current. The voltage feedforward circuit improves transient response. Other features include a sensitive high level enable, over current protection and thermal shutdown. To reduce the complexity of the design and the number of external components, the TPS5430 has an internal feedback compensation loop.
The TPS5430 device is thermally enhanced for easy access in an 8-pin soic powerpadmm package. TI offers evaluation modules and software tools from SWIFTTM designers to help design high-performance power supplies as quickly as possible to meet shorter development cycles.
These devices have limited built-in ESD protection. The leads should be shorted together or placed in a conductive foam placed in the reservoir to prevent static damage to the MOS gate.
Tps5430 internal structure diagram
High current output: 3A (peak 4A);
Wide voltage input range: 5.5~36V;
High conversion efficiency: the best condition is up to 95%;
Wide voltage output range: the minimum can be adjusted to drop to 1.221V;
Internal compensation minimizes the number of external components;
Fixed 500kHz conversion rate;
Overcurrent protection and thermal shutdown function;
With switch enable pin, the off state has only 17uA quiescent current;
Internal soft start Compared with other DC switching power conversion chips of the same type, the high conversion efficiency of the TPS5430 is particularly worthy of attention.
