nPM1300 PMIC: A Practical Design Guide for Embedded Power Management
1. Product Summary The nPM1300 is Nordic Semiconductor’s flagship Power Management IC. One chip replaces five to eight discrete components: a battery charger, two buck regulators, two LDOs or load
The Ultimate Guide to IC Replacement and Component Cross-Reference
Why This Matters You have a BOM. One line has a problem. Maybe the part went NRND. Maybe lead time jumped from 8 weeks to 30. Maybe your procurement team
78xx Voltage Regulator Selection Guide: 7805, 7812, 7815, 7824 & LM317 Comparison
You need a 5V rail for a microcontroller. Your motor driver wants 12V. The op-amp circuit runs best at ±15V. Three different voltages, three different regulator part numbers — and
What Is a PMIC? Power Management Integrated Circuits
Your microcontroller needs 3.3 volts. The memory chip wants 1.2V. The motor driver expects 12V. The sensors run on 1.8V, and the wireless module won’t turn on below 2.5V. That’s
The $1.51 Trillion Semiconductor Squeeze: Why Your BOM Just Got More Expensive
I’ve been tracking semiconductor pricing for years, and I’ve never seen a setup quite like June 2026. The market is projected to hit $1.51 trillion this year. That’s an 89.9%
AI Server Components Sourcing: Power ICs, Memory, Retimers, and Optical Modules
If you’re sourcing components for an AI server build right now, you already know the GPU situation is a headache. That story has been told a hundred times. But here’s
MLCC Supply-Demand Gap and Domestic Substitution: A 2026 Industry Deep Dive
1. First, the Big Picture: What the Hell Is Happening in MLCC? H1 2026 in the MLCC market. Two words: structural mania. Not broad inflation. Not the kind of across-the-board
ADI vs. TI Dual-Phase Buck Controllers for AI Server Power: LTC3880, LTC3882, and TPS536xx Compared
Summary — AI server racks are pushing past 200 kW toward the megawatt scale, and the power delivery architecture that feeds GPU and CPU core rails is under more pressure
