Mingjiada Electronics Supply TI LMR51430 And LMR51606 Synchronous Buck Converters

Shenzhen Mingjiada Electronics Co., Ltd. - Long-term supply of [TI] SIMPLE SWITCHER series synchronous buck converters - LMR51430 and LMR51606. The two products are designed for medium-voltage high-current and high-voltage low-current power supplies, respectively. With their integrated synchronous rectification, low quiescent current and high efficiency, they are widely used in industrial control, communication equipment, automotive electronics, instrumentation and battery power supply systems.

I. LMR51430 – SIMPLE SWITCHER with 40µA IQ ® 4.5V to 36V, 3A Synchronous Buck Converter
1. Overview:
The LMR51430 is an easy-to-use wide VIN SIMPLE SWITCHER power converter synchronous buck converter capable of driving load currents up to 3A. This device has a wide input range from 4.5 V to 36V and is suitable for a variety of industrial applications where power is regulated from an unregulated source.
The LMR51430 operates at switching frequencies of 500kHz and 1.1MHz, supporting the use of relatively small inductors for better solution size. The device has a PFM version for high efficiency at light loads and a FPWM version for constant frequency, and can achieve low output voltage ripple throughout the load range.
2. Main features:
4.5V to 36V input voltage range
3A Continuous output current
Minimum opening time: 70 ns
Fixed switching frequency options at 500kHz and 1.1MHz
