TPP363080-T6TR

Voltage Regulators - DC DC Switching Regulators Overview

The TPP363080-T6TR is a wide-input voltage synchronous buck converter from 3PEAK, designed for high-efficiency power conversion in compact industrial and consumer applications. It features an input voltage range of 4.5V to 36V with a maximum withstand voltage of 42V. The device delivers a continuous output current of 3A and supports an adjustable output voltage range from 0.6V to 34V, maintaining an accuracy of ±2%. Operating at a fixed switching frequency of 400kHz, it integrates high-side (85mΩ) and low-side (45mΩ) power MOSFETs. Key electrical characteristics include a low quiescent current of 90μA, a fixed 2ms internal soft-start time, and protection against over-current, over-voltage, and over-temperature conditions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T6TR' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 400kHz switching frequency variant aligns with your electromagnetic interference (EMI) filtering requirements and inductor selection. Ensure the thermal management design accounts for the TSOT23-6 package limitations under maximum load conditions to maintain junction temperature within the specified -40°C to +125°C operating range.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select the TPP363080-T6TR when a 400kHz switching frequency is preferred over the 1MHz option to potentially reduce component size or cost. This model is appropriate for applications requiring a balance between efficiency and EMI performance. Consider the integrated MOSFET resistance values for thermal calculations. If a different switching frequency or light-load operation mode (PSM vs FPWM) is required, evaluate other variants within the TPP36308 family such as the TPP363081, TPP363082, or TPP363083.

Voltage Regulators - DC DC Switching Regulators Part Context

The TPP36308 series represents 3PEAK's solution for wide-input voltage DC/DC conversion, targeting industrial and consumer markets. It addresses the need for small form-factor power supplies by integrating power switches into a TSOT23-6 package, allowing replacement of larger SOP-8 or TO-220 components. The series supports various topologies beyond standard buck, including inverting buck-boost and iso-buck configurations, providing flexibility for complex power rail generation needs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same family include TPP363081, TPP363082, and TPP363083. Note that these variants differ in switching frequency (1MHz) and light-load operation mode (PSM). Verify compatibility with existing inductors and capacitors, as frequency changes may impact filter design and transient response characteristics.
