Applications
The TL1451ACDRG4 is well-suited for multi-rail power supply designs in industrial equipment, telecommunications infrastructure, and embedded systems requiring dual regulated outputs. Its wide 3.6V to 50V input range makes it ideal for battery-powered devices and systems operating from unregulated DC sources. Designers commonly use it in step-down (buck) and step-up (boost) converter stages where independent control of two output rails is needed.

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.
