PMIC - Supervisors are generally integrated power supply regulators with various of protection circuit. The TPS3510DR is a PMIC - Supervisors product developed by Texas Instruments.

The TPS3510DR is specialized in PC, component, and peripheral application. It is the perfect solution for high efficiency yet reliable power supply with function of overvoltage and overcurrent protection.

This application field is supported by the electrical characteristic of the TPS3510DR. It supports wide input voltage range from 3.2V to 18V, and fast transient response time. It also includes one high-side P-Channel MOSFET and one low-side N-Channel MOSFET, allowing to have up to 4A continuous drain current and 10A pulse current. The device also has integrated programmable current limit protection, which can prevent the circuit from self-destruction caused by over-current issue.

As mentioned above, wide input voltage range, fast transient response time, and powerful current protection are fundamental characteristics of the TPS3510DR in the PC, component, and peripheral application field. With careful design on the power source structure, the TPS3510DR can guarantee voltage and current compliance and ensure a stable yet reliable power supply.

The working principle of TPS3510DR is relatively simple. The output voltage is digitally set in a resistor divider with the pin name of VDD. And the two MOSFETs are switched in an alternate way to enable power transferring between input and output groups, to provide consistent current and voltage level to the load.

The integrated current limit protection is typically used in any application that requires. During the sudden inrush current from the load, the integrated current limit protection will be triggered and close the MOSFET before the positive/negative deflection goes beyond the range set in the device. It can protect the circuit from any potential damage of over-current, and also helps to prevent unexpected downtime caused by over-current issue.

TSPS3510DR is an ideal choice for power supply of the PC, Component, and Peripheral application. It coats with the comprehensive power supply design requirement in the PC, computer and electronics industry with the various protection circuit, ensuring the effective and reliable power supply. As it is already specialized integrated power supply circuit, the design of power supply can be simpler and powerful.
