Frequently Asked Questions
What is the input voltage range of the TL1451ACDRG4?
The TL1451ACDRG4 supports an input voltage range of 3.6V to 50V, with a nominal operating voltage of 6V. This wide range makes it suitable for diverse power supply applications from low-voltage battery systems up to higher-voltage industrial rails.
What control method does the TL1451ACDRG4 use?
The TL1451ACDRG4 uses voltage-mode pulse width modulation (PWM) control. This technique regulates output voltage by adjusting duty cycle based on output feedback, providing predictable loop dynamics and straightforward compensation compared to current-mode control.
How many outputs does the TL1451ACDRG4 support and what package is it in?
The TL1451ACDRG4 is a dual-output PWM controller housed in a 16-pin SOIC (Small Outline Integrated Circuit) surface-mount package. The dual-output capability allows a single IC to manage two independent DC-DC conversion channels simultaneously.
What topologies are supported by the TL1451ACDRG4?
The TL1451ACDRG4 supports both step-up (boost) and step-down (buck) converter topologies, as well as other PWM-based DC-DC conversion configurations. This flexibility enables designers to implement different output voltage levels relative to the input in a single device.
Is the TL1451ACDRG4 RoHS compliant?
The TL1451ACDRG4 carries the JESD-609 code e4, indicating it is a lead-free, RoHS-compliant component. The 'G4' suffix in the part number also denotes compliance with green/halogen-free and RoHS requirements per Texas Instruments naming conventions.
