ST L6727单相PWM控制器应用方案

ST公司的L6726A单相PWM控制器嵌入了大电流驱动器,很容易就能建立起通用的有极好性能的DC/DC降压转换器,成本低.输入电压从5V到12V,输出电压可低至1.5V,可广泛应用于各种子系统的电源如MCH,IOCH和PCI等,存储器和端口电源,CPU和DSP电源以及分布式电源等.本文介绍了L6727和L6726A的主要性能,方框图以及应用电路图.

L6726A Single phase PWM controller
The L6726A and L6727 are low-cost single-phase PWM controllers, with embedded high-current drivers, enabling the easy creation of general purpose DC-DC step-down converters with excellent performance for a broad range of applications – from desktop PC sub-systems, such as memories and chipsets, to general-purpose power supplies. With their high level of integration, these compact SO-8 devices allow a significant reduction in the cost and size of the power supply.

L6726A is a single-phase step-down controller with integrated high-current drivers that provides complete control logic, protections and reference voltage to realize in an easy and simple way general DC-DC converters by using a compact SO-8 package.

Device flexibility allows managing conversions with power input VIN as low as 1.5V and device..
