概述

副端控制用于实现快速瞬态响应
自起动架构免除了增设单独偏置稳压器的需要
专有的栅极驱动编码方案降低了系统复杂性
电流模式控制可确保电流均分
PLL 固定频率：100kHz 至 500kHz
±1% 输出电压准确度
OPTI-LOOP 补偿
采用窄体 16 引脚 SSOP 封装

LTC^®3726 是一款用于同步正激式转换器的副端控制器。当与 LTC3705/LTC3725 栅极驱动器和主端控制器结合使用时，该器件可创建一款兼具 OPTI-LOOP^® 补偿之简单性和副端控制之速度的完整隔离式电源。

LTC3726 的设计目标旨在简化高效率副端正激式转换器的设计。通过与 LTC3705 或LTC3725 配合工作，LTC3726 可形成一款坚固型自起动转换器，因而不必增设在副端控制应用中常用的单独偏置稳压器。此外，该器件还运用了一种专有方案，以通过一个纤巧型脉冲变压器穿越隔离势垒多路复用栅极驱动信号和 DC 偏置电源。

LTC3726 采用 16 引脚 SSOP 封装。

产品详情

Demonstration circuit 1031A-B is a 36V-72Vin, synchronous forward converter featuring the LTC3725 forward converter and the LTC3726 secondary-side controller. This circuit was designed specifically to attain a high current, low ripple, synchronously rectified forward converter to efficiently power 3.3V loads at up to 20A from a typical telecom input voltage range. This circuit features secondary side control of the supply eliminating the need for an optocoupler.
