Elevate Your Power Designs with SLKOR SL27523 — A Trusted Replacement for TI’s UCC27523

Key Specifications of SL27523 Gate Driver

  • Operating Voltage (VDD): Up to 24V
  • Peak Output Current (IO): 4A
  • Low Quiescent Current (IDDq): Only 180μA
  • Wide Temperature Range (TA): Up to 125°C
  • Compact Package: SOP-8 for space-efficient designs

Description

● The SL27523/4/5 series are dual-channel, 4A high-speed low-side gate drivers engineered to efficiently and safely drive MOSFETs and IGBTs. With exceptionally low propagation delay and channel mismatch in a compact SOP-8 package, these drivers enable MOSFETs to switch at frequencies of several hundred kHz. Ideal for synchronous rectification in servers and communication power supplies — where minimizing MOSFET dead time is crucial for converter efficiency — the driver’s dual channels can be paralleled to boost output drive current. In addition, the input thresholds conform to TTL levels and support voltages from -5V to 20V.

● With a broad VDD range of 4.5V to 20V, this device effectively drives MOSFETs or GaN power devices. Its integrated UVLO protection maintains a low output level during abnormal conditions. Additionally, independent input pins tolerate voltages from -5V to 24V, ensuring stable operation despite overshoots from stray inductance. Plus, the input threshold is fully compatible with TTL-level signals.

Applications
 The SL27523/4/5 series gate drivers are built for high-efficiency, high-reliability systems across multiple industries, offering robust performance for both traditional and next-gen applications:

  • AC/DC & DC/DC Converters — Power-efficient designs for industrial and consumer use

How Economics, Sociology & Management Theory Are Powering the Rise of SLKOR & Kinghelm

Image
While groundbreaking innovations like artificial intelligence (AI) have surged forward in recent years, they have yet to ignite the kind of sweeping economic boom seen in a new Kondratieff Wave. Meanwhile, global markets face headwinds from geopolitical tensions, escalating tariffs, and fierce competition in increasingly saturated sectors. In today’s high-stakes landscape, even the slightest misstep can jeopardize a company’s position. Amid this turbulence, SLKOR ( www.slkoric.com ) and Kinghelm ( www.kinghelm.net ) defied the odds—achieving a remarkable 80% compound growth rate in 2024 . Both brands not only expanded their market footprint but also earned growing international recognition as rising leaders in the electronics and semiconductor industries.   At the helm of SLKOR and Kinghelm is Mr. Song Shiqiang , a visionary entrepreneur, grassroots economist, and cultural researcher known for his in-depth studies of Huaqiangbei , China's iconic electronics marketplace.
