【选型】反馈基准电压0.8V的电源芯片VP3478用于辅助电源,宽输入电压范围2.97~40V
在许多工业产品的设计过程中,往往弱电侧需要通过辅助电源进行供电,这时候系统辅助电源处的电路设计就尤为重要。本文推荐昱盛电子推出的DC-DC boost控制器VP3478作为升压电源芯片,在输入电压2.95V~40V之间,可以根据实际需要灵活的输出不同电压,满足设计需要。
图1和图2分别为VP3478的典型应用电路图和内部功能框图:
图1 VP3478典型应用电路图
图2 VP3478内部功能框图
由图1和图2可以看出,昱盛电子的VP3478应用于辅助电源处,有以下优点:
1、宽输入电压范围2.97~40V,这个可以满足不同电压升压需求;
2、VP3478提供0.8V的反馈基准电压,通过该功能可以监测输出电压变化,实现对MOSFET控制动态变化,实现对输出电压的调节;
3、该芯片的COMP可以提供该芯片的开关频率,通过外置电阻和电容方式,可以为VP3478提供100KHz-1MHz频率,实现对不同类型MOSFET进行控制;
对于研发设计者来说,该芯片提供电流监测和电压监测两个环路功能,可以保证芯片可靠工作和输出电压稳定,相比其它的单一电源升压芯片而言,具有更好调节功能。另外该芯片提供了过压,短路,过流,热关断,欠压保护功能,可以确保芯片的可靠性工作;同时对于选用作为升压电路的驱动控制芯片,也可以提供电路的稳定及可靠性。
该芯片可以提供1A的最大峰值电流驱动能力,可以满足对MOSFET驱动设计需求。对于设计者而言,对于封装也是比较关注的,VP3478可以提供MSOP-8和SOIC-8两种封装,供设计者灵活去做设计选择。
所以作为工业产品的设计过程中,昱盛电子推出的电源芯片VP3478可以满足设计者灵活设计需求,同时带来稳定性及可靠性。

LDO和DC/DC有哪些区别?
我们仅从优缺点来做简单的分析 LDO优点:稳定性好,负载响应快。输出纹波小。缺点:效率低,输入输出的电压差不能太大。 DC/DC:直流电压转直流电压。严格来讲,LDO也是DC/DC的一种,但目前DC/DC多指开关电源。具有很多种拓朴结构,如BUCK,BOOST。等优点:效率高,输入电压范围较宽。缺点:负载响应比LDO差,输出纹波比LDO大。 可见LDO只能是降压,DCDC 有升压,降压,升降压多种结构。 由于MOSFET的导通电阻很小,因而它上面的电压降非常低。 如果输入电压和输出电压很接近,最好是选用LDO稳压器,可达到很高的效率。所以,在把锂离子电池电压转换为3V输出电压的应用中大多选用LDO稳压器。虽说电池的能量最后有百分之十是没有使用,LDO稳压器仍然能够保证电池的工作时间较长,同时噪音较低。 如果输入电压和输出电压不是很接近,就要考虑用开关型的DCDC了,应为从上面的原理可以知道,LDO的输入电流基本上是等于输出电流的,如果压降太大,耗在LDO上能量太大,效率不高。 DC-DC转换器包括升压、降压、升/降压和反相等电路。DC-DC转换器的优点是效率高、可以输出大电流、静态电流小。随著集成度的提高,许多新型DC-DC转换器仅需要几只外接电感器和滤波电容器。但是,这类电源控制器的输出脉动和开关噪音较大、成本相对较高。 总的来说,升压是一定要选DCDC的,降压,是选择DCDC还是LDO,要在成本,效率,噪声和性能上比较。
