PTH05050WAZ - 6A 5V-In Wide-Output Adjust PoL Module | Texas Instruments
MPN: PTH05050WAZ ✓ Hoạt độngPTH05050WAZ Tóm tắt
A non-isolated Point-of-Load (PoL) DC-DC module is a fully integrated switching converter that mounts directly next to a load on the same printed circuit board as its load IC, eliminating the intermediate bulk converter stage and the parasitic losses of long power-trace runs. PoL modules sit within the broader hierarchy of DC-DC converters, which in turn belong to the power management semiconductor category that converts and regulates voltage rails in distributed power architectures.
Key features of the PTH05050WAZ include pre-bias start-up for safe paralleling with other supplies, an output ON/OFF inhibit input, Margin Up/Down control pins for board-level testing, Auto-Track sequencing that lets multiple modules ramp together or track an external rail, and the surface-mount through-hole DIPMODULE footprint that combines low-inductance SMT pads with mechanical through-hole pins. The wide-output-adjust range (0.8 V to 3.6 V) covers the core voltages of modern DSPs, FPGAs, ASICs, and DDR memory rails.
Architecturally, the PTH05050WAZ is built around a synchronous buck topology with integrated power MOSFETs, a power inductor, and control IC all inside the module body. This integration removes the need for external magnetics design and significantly reduces radiated EMI by keeping the high-di/dt loop inside the package, while still delivering high efficiency across the 4.5 V to 5.5 V nominal 5 V intermediate bus.
Typical applications include 5 V intermediate-bus architectures powering low-voltage DSPs, FPGAs, ASICs, and DDR memory; telecom and networking line cards requiring sequenced multi-rail power; industrial controllers and distributed-power systems; and any board that needs a compact, high-efficiency point-of-load converter with sequencing and margining built in.
When designing with this part, follow the manufacturer's recommended input/output capacitor values, sequence rails using Auto-Track, and pay attention to derating at high ambient temperatures above 55 °C. The PTH05050WAZ is a member of the well-known TI PTH/POL family, making it drop-in compatible with several 6 A, 5 V-input siblings.

Ứng dụng tiêu biểu
PTH05050WAZ phù hợp cho 6 Áp dụngs: FPGA Core and Auxiliary Rail Power, DSP and ASIC Multi-Rail Power, Telecom and Networking Line Cards, Industrial Distributed Power Systems, DDR Memory Power (VDDQ and VTT), Test and Measurement Instrumentation.
FPGA Core and Auxiliary Rail Power
The PTH05050WAZ is well matched to mid-range FPGA core voltage rails thanks to its 6 A continuous output, 0.8 V to 3.6 V adjustability, and 5 V intermediate-bus input. The wide output range covers common FPGA core voltages (0.85 V, 1.0 V, 1.2 V) and auxiliary rails (1.8 V, 2.5 V, 3.3 V) without intermediate converter stages. Auto-Track sequencing enables coordinated power-up between core and I/O rails, eliminating in-rush current spikes that can stress FPGA power-input structures. Efficiency up to 95% at typical load reduces thermal dissipation in space-constrained FPGA boards.

DSP and ASIC Multi-Rail Power
DSP and ASIC systems typically require sequenced core, I/O, and PLL rails that must come up in a specific order. The PTH05050WAZ's Auto-Track feature allows the output to track an external reference or other PTH/POL modules, simplifying multi-rail sequencing without dedicated sequencer ICs. The 0.8 V to 3.6 V adjustability covers 1.0 V DSP cores, 1.8 V DDR2, and 3.3 V I/O from a single 5 V bus. The 21.6 W output power budget is sufficient for mid-range DSPs and ASIC power domains.
Được đề xuất
Telecom and Networking Line Cards
Telecom and networking line cards require multiple isolated or non-isolated rails with tight sequencing for hot-swap and brown-out recovery. The PTH05050WAZ accepts the standard 5 V intermediate bus common in distributed telecom architectures and produces any rail from 0.8 V to 3.6 V. Pre-bias start-up capability allows the module to safely drive into pre-charged loads, which is essential for hot-swap and redundant-power applications. The 6 A output handles processor, ASIC, and memory bank power on a single card.
Được đề xuất
Industrial Distributed Power Systems
Industrial controllers and distributed-power systems use a 5 V or 12 V intermediate bus with multiple PoL converters feeding individual ICs. The PTH05050WAZ is purpose-built for the 5 V bus segment, providing 6 A at 0.8 V to 3.6 V for sensor interfaces, microcontrollers, and communication transceivers. Its operating temperature range of -40 °C to +85 °C supports industrial environments, and the through-hole pins provide mechanical robustness for vibration-prone installations. Auto-Track simplifies firmware-controlled power sequencing in PLC and motor-drive controllers.

DDR Memory Power (VDDQ and VTT)
DDR, DDR2, and DDR3 memory systems require precisely regulated VDDQ and VTT rails with tight tolerances and pre-bias start-up behavior to prevent back-powering through the data buffers. The PTH05050WAZ's pre-bias start-up feature ensures safe operation into pre-charged memory rails, while its 0.8 V minimum output covers 0.9 V DDR2 VTT and 1.5 V DDR3 VDDQ. The 6 A output drives multi-bank memory configurations on a single module. Margin Up/Down pins allow board-level margining during test.
Được đề xuất
Test and Measurement Instrumentation
Test and measurement equipment requires low-noise, well-regulated supplies with margining capability for automated production test. The PTH05050WAZ's Margin Up/Down control pins allow direct voltage margining for ATE without external DACs, while its 5 V input integrates with standard instrumentation power architectures. The 6 A output handles multiple supply rails from a single converter. High efficiency (up to 95%) reduces internal chassis heating that would otherwise require fans or larger heatsinks in sealed bench instruments.

- Integrated power inductor and MOSFETs inside the module (vsDiscrete buck converter designs with external L and FETs)
- Pre-bias start-up allows safe hot-plug into pre-charged loads (vsConventional POL modules that sink current at start-up)
Ghi chú thiết kế
Estimated: at Vin=5 V, Vout=1.8 V, and 6 A full load, the PTH05050WAZ dissipates approximately (5-1.8) × 6 = 19.2 W worst-case, but at the datasheet's 95% efficiency the actual dissipation drops to about 0.6 W. Mount on a minimum 1 oz copper pour with thermal vias underneath the through-hole pin pads to keep the case below +85 °C at 25 °C ambient. For enclosed or high-ambient installations, add 100-200 LFM forced-air cooling or upgrade to the 10 A PTH05060WAZ for additional thermal headroom.
Place input and output ceramic capacitors (typically 22 µF X5R minimum) as close to the module pins as possible to minimize high-di/dt loop inductance. Use wide copper pours (≥ 0.5 inch wide) for Vin and Vout traces, and add a stitched ground plane directly under the module. The through-hole pins must be soldered for both electrical connection and thermal dissipation - do not rely solely on the SMT pads for high-current paths.
Do not apply more than 5.5 V to the Vin pins - the internal MOSFETs are 6 V rated and transient overshoot can cause catastrophic failure. When using Auto-Track sequencing, ensure the track source ramps monotonically from 0 V to its final value; glitches can cause the output to overshoot or latch up. The Inhibit pin is not 5 V tolerant logic - use a pull-up to a 3.3 V or 5 V rail through a 10 kΩ resistor, not directly to Vin.
Thông tin tuân thủ
Z suffix indicates Pb-free, RoHS-compliant terminations per TI material declaration. Base PTH05050W (no Z) is SnPb and not RoHS-compliant. Not qualified to AEC-Q100; for automotive PoL applications, look at TPS54xxx automotive-grade switching regulators.
