LM2576/LM2576HV的特性:
1)有3.3V、5V、12V、15V和可调电压输出多种系列;
2)输出电压可调范围1.23V-37V (HV型号的可达57V)，负载电压的输出容差最大为±4%;
3) 少只需要4个 组件，可达3A的输出大电流
4)较寛的输入电压范围，HV型号甚至可达40V～60V;
5)内部振荡器产生52KHz固定频率;
6)可用TTL电平关闭输出，低功耗待机模式，典型待机电流为50μA;
7)BUCK式降压器，较高的转换效率;
8)过热和过流保护;
9)可实现Buck-Boost式正-负电压转换器。
LM2576/LM2576HV引脚功能说明:
1)VIN—输入电压端，为减小输入瞬间电压和给调节器提供开关电流，此接脚应接旁路电容CIN;
2)OUTPUT—稳压输出端，输出高电压为(VIN-VSAT)，输出低电压为-0.5V。
3)GND—电路地;
4)FEEDBACK—反馈端;
5)ON/OFF—控制端，高电平有效，待机静态电流仅为75μA
