The TB7101F(T5L3.3,F) is a DC DC Switching Regulator designed with a highly efficient current mode control. It provides excellent dynamic characteristics with low output voltage ripple, while also accommodating a wide range of input supply voltages and output current capability. In addition, it features thermal shutdown protection, input over voltage protection, output current over-load protection, and AC line noise protection.

Integrating its main controller, a PWM control chip, the TB7101F(T5L3.3,F) can convert an input voltage of 5.4V to 37V into an output voltage of 0.6V to 5.0V. This enables the user to easily set various output voltages with a single part, and a single point of adjustment. The output voltage can be adjusted using a voltage divider.

The TB7101F(T5L3.3,F) is widely used in notebook computers, industrial instrumentation, telecommunication equipment and other portable electronic devices. It is designed to reduce the size and weight of the host equipment, and it offers high performance with low cost. The targeted applications include power supplies, portable power sources, automotive electronics, and medical technology.

The working principle of the TB7101F(T5L3.3,F) is based on a switching regulator topology with a built-in PWM control chip, together with an adjustable two-wire programmable output voltage control. In the working state, the PWM control chip is constantly monitoring the changing voltage of the load side and adjusting the output voltage accordingly. In addition, the update rate of the PWM control chip has been optimized to ensure a reliable, stable, and efficient output.

In order to further enhance the overall performance of the DC DC Switching Regulator, a wide variety of external components such as capacitor, inductor, diode, and resistor can be used for charging, discharging, filtering, and EMI suppression when necessary. An external clock can also be used to create a faster and smoother switching waveform.

By utilizing the TB7101F(T5L3.3,F) and all its components, a constant output voltage can be maintained, while the output current ripple can be minimized. This means that, in any given application, the TB7101F(T5L3.3,F) can provide a more reliable and efficient power supply than many other competing products in the market.
