TPS62184YZFR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62184YZFR is a synchronous step-down DC-DC converter from Texas Instruments, designed for low-profile power rails. It operates with an input voltage range of 4 V to 17 V and delivers up to 6 A of output current using two identical, current-balanced phases. The device features a fixed switching frequency of 1.5 MHz, ensuring high efficiency across the load range. It includes integrated power good indication, 1% accuracy regulation, and adjustable soft start capabilities. The component is housed in a compact DSBGA package and supports an operating junction temperature range from -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix YZFR against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the DSBGA package. Cross-reference the ordering part number with official Texas Instruments documentation to avoid substitution errors. Confirm that the required operating temperature range aligns with your application environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a dual-phase solution is required to handle high currents while minimizing input capacitor size. The 1.5 MHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 1% accuracy requirement for sensitive loads. Evaluate the thermal dissipation needs based on the DSBGA package limitations under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6218x family of synchronous buck converters. It is distinct from single-phase variants by its dual-phase design, which enhances transient response and efficiency at high loads. The YZFR suffix indicates the specific DSBGA package and reel packaging configuration provided by Texas Instruments for surface-mount assembly.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the TPS62183 or TPS62185, depending on current requirements. Verify that any alternative maintains the 4V to 17V input range and 1.5 MHz switching frequency. Ensure the replacement offers equivalent thermal performance and package dimensions.
