Mainly listed as follow:

industrial supply 12v 1.General power supply,also includes:switching power supply,inverter power supply,DC power supply,regulated power supply,communication power supply,module power supply,variable frequency power supply,UPS power supply,EPS emergency power supply,purifying power supply,PC power supply,rectifier power supply,customized power supply,heating power supply,welding power supply/Arc power supply,plating power supply,network power supply,electric operation power supply,adapter power supply,linear power supply,power supply controller/driver,power supply and other general power

industrial supply 12v 2.Specified power supply, also includes: security power supply,high-voltage power supply,medical power supply,military power supply ,aviation power supply,laser power supply and other specified power supply
Characteristic:
power supply are with many different kinds,the common characteristics are as follow:
1)Low working voltage: the general working voltage is 3.0-3.6v. some working voltage are even lower,such like 2.0,2.5,2.7v;some are 5v and some are special voltage with 12v or 28v
2)Small working current: because of most electronic products working current is small than 300mA, so 30~ 300mA power IC takes up bigger ratio in specific and quantity
3) Small size: Recently,the developed portable products all adopt chip type device also includes power IC,mainly includes SO sealed packin,SOT-23 sealed packing,μMAX sealed packing and the smallest size SC-70 and the latest SMD sealed packing, making the space of power become smaller and smaller.
4) Comprehensive protection measures: New type power IC with comprehensive protection measures,including: output over current limited,over-heat protection,short-circuit protection and the wrong connetion of battery magnetic protection,making the power operation safe and reliable, is not easy to damage.
5)Low power consumption and power off function:New type power IC static electricity is small,generally is hundreds of μA,some static electricity of micro power loss linear regulator is only 1.1μA. Furthermore,some power IC with function of cut off the power control terminal,when the power is at the status of cut off,IC itself power consumption is about 1μA.it can save much electric energy due to it can make parts of circuit not work.Example,in a wireless communication device,it can close off receiving circuit when it's at the status of sending;it can close off indicating circuit when without receiving the signals.
6)With power working signals output: many portable electronic products are with single chip microcomputer,when due to the power is over-heat or low battery voltage to make the output voltage decrease some percentage, the power IC will transmit a power working status signal to sing chip microcomputer,making the single chip microcomputer reset. using this signal also can make the power working status indication(when the battery is low voltage,there is LED indicate)
7) High output voltage precision: the general output voltage precision is between ±2~4%, many new type power IC precision can reach ±0.5~±1%;and the temperature factor of output voltage is small.usually is ±0.3~±0.5mV/°C,some can reach the level of ±0.1mV/°C,linear adjusted rate is usually 0.05%~0.1%/V,some can reach 0.01%/V;load adjusted rate is usually 0.3~0.5%/mA,some can reach 0.01%/mA.
8)New combination type power IC: booster type DC/DC converter efficiency is high but wave,noise and voltage is big,low voltage linear regulator efficiency is low but noise is small,the dual output power IC after combine these two,can well solve the problems of efficieny and noise.Example, digital circuit part adopt booster type DC/DC converter power and adopt LED power when the circuit is sensitive to noise, the power IC includes MAX710/711,MAX1705/1706 and ect. another example is charge pump, the power IC output voltage charge pump,such like MAX868,it can output 0~-2VIN adjusted constant voltage,and supply 30mA current;MAX1673 constant voltage type charge pump power IC output same voltage
