TPS5430DDAR Package: SOIC-8-EP DC-DC power chip, TI original stock
describe
TPS543x is a high output current PWM converter that integrates a low resistance, high side N-channel MOSFET. A high-performance voltage error amplifier is included on the substrate with the listed features, providing strict voltage regulation accuracy under transient conditions; The low voltage output circuit prevents startup until the input voltage reaches 5.5V; An internally designed slow start circuit to limit surge current; And a voltage feedforward circuit to improve transient response. Using the ENA pin, the power off current is usually reduced to 15 μ A. Other functions include active high enable, overcurrent limitation, overvoltage protection, and thermal shutdown. In order to reduce design complexity and external component count, the TPS543x feedback loop has been internally compensated. TPS5431 is designed to run from the power track to 23V. TPS5430 regulates multiple power sources, including 24V bus.
The TPS543x device has a heat enhanced, easy-to-use 8-pin SOIC PowerPAD integrated circuit package. TI provides evaluation modules and design software tools to help quickly achieve high-performance power supply designs to meet active device development cycles.
