TPS6735ID

TPS6735ID Description

The TPS6735ID from Texas Instruments is a fixed-output, negative-voltage buck switching regulator designed to deliver -5V at 200mA from an input voltage range of 4V to 6.2V. Housed in an 8-pin SOIC package, this surface-mount IC operates at a switching frequency of 160kHz, making it suitable for compact, power-sensitive designs. With a non-synchronous rectifier topology, it provides efficient voltage conversion while maintaining simplicity in circuit implementation. The device is RoHS3 compliant, REACH unaffected, and rated for MSL 1 (Unlimited), ensuring reliability in industrial and commercial environments.

TPS6735ID Features

• Negative Output Configuration: Generates -5V from a positive input, ideal for biasing applications.
• Wide Input Range (4V–6.2V): Supports common power rails like 5V systems.
• Compact and Efficient: 160kHz switching frequency balances size and performance, reducing external component count.
• Robust Compliance: Meets ROHS3, REACH, and EAR99 standards for global deployment.
• Low Quiescent Current: Optimized for battery-powered or energy-efficient systems.
• Non-Synchronous Design: Simplifies layout and reduces cost compared to synchronous alternatives.

TPS6735ID Applications

• Industrial Control Systems: Negative rail generation for op-amp circuits, sensors, and data acquisition.
• Test and Measurement Equipment: Precision power supplies requiring stable -5V bias.
• Portable Electronics: Space-constrained devices like medical monitors or handheld instruments.
• Telecom Infrastructure: Power management for RF components and signal conditioning circuits.
• Automotive Electronics: Auxiliary power in infotainment or ADAS modules (within input voltage limits).

Conclusion of TPS6735ID

The TPS6735ID stands out for its simplicity, efficiency, and reliability in generating negative voltages from low-input rails. Its compact SOIC package, wide compliance, and low-noise operation make it a preferred choice for designers needing a cost-effective, space-saving solution. Whether for industrial, portable, or precision analog systems, this regulator delivers consistent performance with minimal external components. Texas Instruments’ reputation for quality further ensures its suitability for demanding applications.
