激光测距望远镜就是通过激光二极管发射激光，光电二极管接收激光信号，通过计算信号从发射到接收所用的时间，从而计算出观测者到目标的距离，某客户在设计激光测距望远镜时，采用3V锂电池供电，由于后续的系统有更高压的需求，客户打算将3V升压到5.5V给其它器件供电，给客户推荐了圣邦微的升压DCDC SGM6603。

应用框图如下：

SGM6603主要有以下优势：

输入电压0.9V-5.5V，输出电压可调，最高输出电压可达5.5V，能满足客户输入输出需求。
功耗低，SGM6603静态电流仅为30μA，关断电流低至1μA，可以延长电池的使用寿命。
SGM6603A的转换效率可达90%，工作模式为强制PWM模式，即使在轻负载下也保持着1.2MHZ恒定的开关频率，可以减少输出纹波和避免噪声干扰。
采用SOT23-6的小封装设计，减少了PCB板的面积，更有利于产品的小型化设计。

综上所述，SGM6603具有低功耗，高效率，小封装等特点，可以满足客户激光测距望远镜系统供电设计需求。

【应用】国产APD升压芯片SGM41283用于长距离光模块，容差不超过5%，输出电压范围最高达到70V

在长距离光模块中，普通PIN二极管无法实现对弱光信号的接收，通常采用APD来完成接收。光模块一般使用的3.3V供电，APD需要20V及以上的电压，且需要对电流进行监控，所以需要一款电流监控DCDC升压芯片。本文推荐圣邦微的APD升压芯片SGM41283。

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。

实际设计中根据什么条件选择使用DCDC还是LDO？

具体还是由应用类型决定。如升压只能选DCDC，降压根据情况来选择；接着看重性能还是效率、并根据负载类型的不同选型。如对要求高效率的应用您可以选择DCDC，而选LDO可为噪音比较敏感的模拟电路提供干净电源。
