TPS56300PWP

Overview

The TPS56300PWP is a dual-output low-input-voltage DSP power supply controller manufactured by Texas Instruments. It features a wide input voltage range of 2.8V to 5.5V and supports programmable output voltages via Voltage Identification (VID) pins, accommodating nine preset voltage pairs from 1.3V to 3.3V. The device utilizes synchronous buck topology for high efficiency exceeding 90%. It incorporates hysteresis control with droop compensation for rapid transient response and includes comprehensive protection mechanisms such as overvoltage, undervoltage, and adjustable overcurrent protection.

Feature Summary

• Dual-output architecture designed specifically for powering digital signal processor cores and I/Os
• Programmable output configuration through Voltage Identification (VID) pins
• Integrated hysteresis control with droop compensation for fast transient response
• Comprehensive protection suite including overvoltage, undervoltage, and adjustable overcurrent limits

Applications

• Powering core and I/O rails in C6000 series Digital Signal Processors
• Split voltage systems requiring synchronized power-up sequencing
• Low-input-voltage DC/DC conversion for embedded DSP applications

Procurement Notes

Verify the specific suffix 'G4' if environmental compliance is required, as standard versions may differ. Confirm package availability in HTSSOP-28 format. Check current lifecycle status as legacy components may have limited production support. Ensure design-in documentation matches the exact pinout and thermal requirements for the target PCB layout.

Selection Notes

Select this component when designing power supplies for split-voltage DSP systems requiring precise core and I/O voltage regulation. It is suitable for applications needing a wide input range between 2.8V and 5.5V. Consider its synchronous buck topology for efficiency needs and VID pin flexibility for multi-voltage configurations without external resistors.

Part Context

This part belongs to the TPS56300 family of dual-output controllers. It shares functional similarities with the TPS56302 but differs in specific parameter sets. It is distinct from LDO regulators like the TPS70145, offering higher efficiency through switching rather than linear regulation. The PWP suffix indicates the HTSSOP-28 package variant.

Replacement Considerations

Direct substitutes include other members of the TPS5630x family, such as the TPS56302, which offers similar dual-output capabilities. Verify compatibility regarding VID pin configurations and thermal performance before substitution.
