Working Principle of TPS43000PWRG4
The TPS43000PWRG4 is a PWM switching regulator that follows a basic switched-mode power conversion design with a fixed frequency operation and a high-power-factor. Its output voltage is regulated by sensing an external resistor divider and an on-chip amplifier, modulating the switch on-time proportionally to the output voltage.
The TPS43000PWRG4 also features an over-current protection and a short-circuit protection feature. When the programmed current limit is exceeded, the device will pulse-by-pulse or latch-off to limit the current. This is especially useful in applications with no external current limiting or short-circuit protection circuit. It also has synchronous rectifier control, which allows for improved efficiency by replacing the rectifier diode with a low-cost FET controller.
