概述

Description

PTN78020HAZ is a Texas Instruments high-current, multiphase, synchronous buck regulator in a compact HAZ package. It’s designed for point-of-load applications such as CPU/GPU cores, memory, and FPGA/ASIC rails.
Key points:
- Integrates high- and low-side MOSFETs and switching controller for efficient DC-DC conversion.
- High output current capability (tens of amps, ~20 A class) with fast transient response.
- Output voltage is adjustable via external feedback resistors; supports multi-phase operation to reduce ripple.
- Built-in protections: current limit, over-temperature, and fault/power-good signaling; enable input; optional remote sensing.
- Suitable for tight footprint designs requiring reliable, low-noise core rails.
Typical use: generate low voltage rails from a higher input supply for modern digital cores.
Note: exact electrical specs (input range, output range, accuracy, efficiency, pinout) vary by variant. Always consult the PTN78020HAZ datasheet and TI product page for precise information.

Package

HTSSOP-16 package with an exposed/thermal pad (TI package code HAZ).

Pinout

- Pin count: 28 pins (28-pin package)
- Function: 20-A, synchronous buck DC-DC regulator (point-of-load regulator) used to convert a higher input voltage to a lower regulated output for system rails.

Application

PTN78020HAZ is a high-current point-of-load (POL) DC-DC converter module. Typical applications include:
- CPU/GPU/FPGA/ASIC VRMs in servers, workstations, and data centers
- Telecom and networking equipment (switches/routers/base stations)
- Storage systems and embedded systems
- Industrial automation and motor-control power rails

Equivalent

I can help, but I need the specs. Please provide or confirm:
- VIN range, VOUT, IOUT
- package/pinout (e.g., 8-SOIC, QFN)
- efficiency/temperature range
- whether you need pin-for-pin compatible replacement
With the datasheet or these parameters, I can suggest exact cross-references. Without them, replacements vary by vendor and footprint.
