The TC1303B-SD0EMFTR is a linear + switching voltage regulator from the range of power management integrated circuits (PMICs). This particular regulator, released by Toshiba, implements a broad range of features specifically designed to help improve power efficiencies in multiple applications. By employing both linear and switching techniques, the TC1303B-SD0EMFTR voltage regulator is able to maintain optimal power delivery, even when the battery voltage is on the lower side.

Overview of the TC1303B-SD0EMFTR Application Field

The TC1303B-SD0EMFTR’s wide range of features makes it suitable for use in a variety of applications, such as portable equipment, computers, home and office appliances. This voltage regulator is particularly ideal for battery-powered and low-current device applications due to its high power efficiency and low-drop-out operation. By providing both linear and switching capabilities, the TC1303B-SD0EMFTR can be used to supply stable voltage, even in environments where the incoming and discharged voltages are relatively low.

Features of the TC1303B-SD0EMFTR

The TC1303B-SD0EMFTR comes with a frequency-switched-mode control that allows it to efficiently regulate output during relatively low battery voltage conditions. Moreover, the integrated charge pump circuitry used in the TC1303B-SD0EMFTR helps reduce current consumption to 0.2μA during standby mode. This amplifier also supports several programmable features, such as adjustable voltage accuracy, adjustable raise time and adjustable output switch-down pressure, making it more desirable in applications where fine-tuning is required.

TC1303B-SD0EMFTR Working Principle

The TC1303B-SD0EMFTR is based on a system comprising an oscillator, PWM (pulse-width-modulated) controller, charge pump and FETs (field-effect transistors). The system starts to work from the oscillator stage, where the TC1303B-SD0EMFTR amplifies the battery voltage and produces an adjustable frequency. The output voltage of the oscillator is then fed to the PWM controller, which adjusts the duty ratio based on the battery voltage. The duty ratio is then used as the basis of the transistor switching, with the charge pump working to achieve the desired drive voltage. Last but not least, the FETs act as switches to turn the charge pump current on or off depending on the voltage status.

Conclusion

The TC1303B-SD0EMFTR is a linear + switching voltage regulator from Toshiba that is suitable for use in multiple applications requiring precise power delivery. By employing both linear and switching techniques, it is able to accurately maintain optimal power delivery, even at lower battery voltages. The numerous programmable features integrated into the TC1303B-SD0EMFTR makes it an even more attractive choice for applications requiring fine-tuning of output voltages. Furthermore, the charge pump circuitry used in this amplifier helps reduce current consumption to 0.2μA during standby mode, thus making it an ideal option for battery-powered and low-current device applications.
