Key Features
- Dual hysteretic current-mode control with 4.5V to 25V input range enabling fast transient response without loop compensation design in dual output point-of-load converters
- Dual synchronous step-down switching controller with individual channel control supporting independent output voltage regulation for multi-rail power supply designs
- Compact 30-pin TSSOP package (R-PDSO-G30) with hysteretic control technique simplifying PCB layout and reducing total component count compared to traditional voltage-mode controllers
Applications
The TPS5602IDBTG4 is designed for dual-output point-of-load (POL) power conversion in networking equipment, telecom infrastructure, and server blade power distribution systems operating from 12V or 24V bus rails. Its hysteretic current-mode control eliminates compensation network complexity, making it ideal for rapid prototyping and designs where fast load transient response is critical such as FPGA core power, DDR memory termination, and DSP power supplies. Industrial automation controllers, medical instrumentation power modules, and communications equipment also benefit from the dual independent buck controller architecture for efficient multi-rail DC-DC power conversion.

Frequently Asked Questions
What control mode does the TPS5602IDBTG4 use?
The TPS5602IDBTG4 uses hysteretic current-mode control (Control Technique: HYSTERETIC CURRENT MODE), which provides inherently fast transient response and simple loop stability without requiring external compensation components. This control architecture automatically adjusts switching frequency based on load conditions, simplifying design and improving dynamic performance.
What is the input voltage range of the TPS5602IDBTG4?
The TPS5602IDBTG4 accepts input voltages from 4.5V to 25V (nominal 7V), supporting common 5V, 12V, and 24V power bus rails used in industrial, telecom, and computing applications. This wide input range allows the controller to be used across various system architectures without requiring different power supply designs.
What package does the TPS5602IDBTG4 use?
The TPS5602IDBTG4 is housed in a 30-pin TSSOP package (JESD-30 Code: R-PDSO-G30), a small thin-shrink small-outline surface-mount package. This compact package accommodates the dual-channel controller circuitry with sufficient pin count for independent control signals, feedback inputs, and gate drive outputs for both switching channels.
What are typical applications for the TPS5602IDBTG4?
Typical applications include dual-output point-of-load converters for FPGA core and I/O power, DDR memory power rails, multi-rail server power distribution, networking switch power supplies, and DSP subsystem power management. The dual controller also suits industrial motor drive auxiliary supplies and telecom rack unit power conversion requiring independent dual step-down regulation.
Is the TPS5602IDBTG4 RoHS compliant?
Yes, the TPS5602IDBTG4 is RoHS compliant (JESD-609 Code: e4), indicating a lead-free and RoHS-conforming component finish. This ensures compliance with EU RoHS Directive requirements and suitability for environmentally regulated markets and modern lead-free PCB assembly processes used in commercial and industrial electronics manufacturing.
