60V wide-input non-synchronous buck converters are widely used in automotive and industrial power designs. They eliminate the internal low-side MOSFET to reduce cost and simplify driving. With 60V tolerance, they support 12V, 24V, and 48V buses – suitable for body controllers, industrial panels, and more.
Five domestic suppliers offer differentiated options across current, frequency, package, and grade:
SGMICRO SGM61606-ADJQ – 600mA, 2.1MHz, 33μA quiescent, TSOT-23-6, AEC-Q100 Grade1. Lowest power and smallest footprint (~15mm²), ideal for compact automotive sensor modules. Built-in compensation, 97% max duty cycle, PFM at light load.
3PEAK TPP60308 – 3.5A, adjustable 100kHz–2.5MHz, external sync, ESOP8 with thermal pad. External compensation allows tuning for industrial loads with frequent transients. 80mΩ integrated FET, foldback frequency protection.
Silergy SY8401ABC – 800mA, fixed 1.2MHz, SOT-23-6. Adaptive constant off-time with peak current control for fast load response. 0.6V precision reference, hiccup protection for unattended industrial gear. 50V max input – suitable for 24V bus equipment.
Shanghai Belling BL9366 – 600mA, 480kHz, SOT23-6. Low-cost, high-volume solution. 90% peak efficiency, 0.1μA shutdown current – ideal for battery-powered appliances and entry-level industrial tools.
JWQ5125 – 5A, AEC-Q100 Grade1, ESOP8. High current margin for 15-year automotive life. Unique current-loss protection, UVLO, and full thermal/overcurrent safeguards – suited for domain controllers, lighting, and infotainment.
From ICgoodFind: From tiny 600mA sensors to 5A domain controllers – domestic buck converters now cover the full spectrum. Engineers can match current, frequency, and grade to their specific automotive or industrial project needs.
