Linear & Switching Voltage Regulators

TPS56302PWP Description

The TPS56302PWP from Texas Instruments is a dual-output, synchronous step-down DC/DC converter with an integrated sequencer, designed for high-efficiency power management in compact applications. Housed in a 28-pin HTSSOP package, this IC combines a 2A programmable buck regulator (Output 2) with a controller for an additional buck/linear regulator (Output 1), offering flexibility in power architecture. Operating from a 2.8V to 5.5V input range, it delivers stable outputs with a switching frequency of 300kHz, optimizing performance for space-constrained designs. Though marked Obsolete, it remains relevant for legacy systems due to its robust design, ROHS3 compliance, and REACH-unaffected status.

TPS56302PWP Features

• Dual-Output Design: Combines a 2A buck regulator and a controller for secondary regulation, enabling multi-rail power solutions.
• Integrated Sequencer: Simplifies power-up/down sequencing, critical for processors and FPGAs.
• Wide Input Range (2.8V–5.5V): Supports low-voltage sources like Li-ion batteries or 3.3V/5V rails.
• 300kHz Switching Frequency: Balances efficiency and component size, reducing external filter requirements.
• Surface-Mount HTSSOP Package: Ideal for high-density PCB layouts.
• Robust Compliance: ROHS3, REACH, and EAR99 certifications ensure environmental and export compatibility.

TPS56302PWP Applications

• Embedded Systems: Power sequencing for microcontrollers, DSPs, or FPGAs in industrial controls.
• Portable Electronics: Battery-powered devices requiring multi-rail regulation (e.g., handheld test equipment).
• Legacy Upgrades: Replacing discrete power solutions in existing designs due to its integrated sequencer.
• Distributed Power Architectures: Secondary voltage regulation in telecom or networking hardware.

Conclusion of TPS56302PWP

The TPS56302PWP excels in applications demanding dual-output flexibility, sequenced power delivery, and compact footprints. While obsolete, its programmable output, integrated sequencer, and compliance features make it a pragmatic choice for legacy or niche designs. Engineers valuing reliability and simplified power management in constrained environments will find this IC particularly advantageous. For new designs, consider TI’s active alternatives with updated features.
