DC DC Switching Controllers datasheet and documents for TL1451ACNSN

TL1451ACNSN

DC DC Switching Controllers Overview

The TL1451ACNSN is a dual-channel pulse-width modulation (PWM) control circuit manufactured by Texas Instruments. It integrates all functions required for two PWM controllers on a single monolithic chip, including an internal 2.5 V regulator, two error amplifiers, a programmable oscillator, and dead-time comparators. Designed for non-isolated topologies such as boost, buck, and flyback, it supports positive output configurations with transistor drivers. The device operates within a supply voltage range of 3.6 V to 50 V and features a switching frequency range from 1 kHz to 500 kHz. It utilizes a 16-SSOP package and is rated for an operating temperature range of -40°C to 85°C.

DC DC Switching Controllers Feature Summary

Integrates complete dual PWM power control circuits on a single chip
Provides fully synchronous operation capability with adjustable dead-time control
Includes internal undervoltage lockout and short-circuit protection mechanisms

DC DC Switching Controllers Applications

Dual-output DC-DC converter designs
Synchronous rectification applications
Industrial power supply systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'SN' against the official Texas Instruments datasheet to confirm the exact package type and temperature grade. Ensure compatibility with the intended PCB footprint for the 16-SSOP configuration. Confirm that the component meets the required environmental standards for the target application before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when designing dual-channel power supplies requiring precise synchronization and adjustable dead-time control. It is suitable for applications needing wide input voltage ranges and integrated protection features. Consider the thermal performance and package constraints associated with the SSOP form factor during the design phase.

DC DC Switching Controllers Part Context

The TL1451A series serves as a versatile solution for complex power management tasks. This specific variant belongs to the broader family of dual PWM controllers offered by Texas Instruments. It shares core architectural similarities with other members like the TL1451CN and TL1451ACPWR but differs in packaging and specific operational ratings.
