AC-DC conversion chip: responsible for converting alternating current to direct current, such as the chip used in the aforementioned power adapter or power module. DC-DC conversion chip: Includes various forms of converters, such as Buck (Buck) converter, Boost (Boost) converter, and buck-boost (Buck) converter chip. < / p > < p > common power management chip are HIP630IS653RT923ADP316KA7500, TL494, etc. Power management is described in detail belowThe main types of chips, and illustrate four common power management chips.
SGM4151, the chip is a high-efficiency power management chip for portable devices and low-power applications for battery-powered devices.
The main power management chips are dual-in-line chips, and some are surface-mount packages, among which HIP630x series chips are more classic power management chips, designed by the famous chip design company Intersil.
Pin power management chip models include PF7001S PF7001 SOP and U32kHz. Pin number 6, package TO-220-7, installation mode ThroughHole.
-5V. top256yn is a high-voltage switching power supply IC, in which the 1-pin voltage working range of 3-5V, the working period is not beyond this range. Scope is the boundary, sphere of activity, and sphere of influence above and below.
IGBT type used in the high pressure plate of M3-L234E inverter microwave ovenNumber is IRG4PC50U.
LNK364PN is a low-power high-efficiency off-line switching IC, often used as a power management chip for induction stoves, with high circuit efficiency. The chip can be directly replaced with LNK564PN, or replaced with TNY266, and the first pin is suspended with 0.1UF/63V capacitor to the ground.
The circuit board MCU near the 8-pin chip, may be 24c02 or other memory with larger storage space. Used to save the Settings before the power failure. Start up again, read its internal data first, and work according to the saved data.
LNK364PN. According to the query of the relevant information of the United States microwave oven, the integrated block of the United States microwave oven frequency conversion board is LNK364PN model. The oven capacity of the variable frequency microwave oven is increased by more than 20% and can be put into a larger plate.
System-level Power Management Unit (SPM) : The System-level power management unit (SPM) is a highly integrated power management solution that integrates multiple power management functions such as voltage regulation, battery charging, load switching, and morePower distribution, etc.
SGM4151, the chip is a high-efficiency power management chip for portable devices and low-power applications for battery-powered devices.
, LM7805, etc. 7-pin power chip Model 8370 is a commonly used power management chip, mainly used for power supply management of electronic equipment. With over voltage, under voltage, over current, short circuit protection and other functions, support a wide range of input voltage.
RT8480. According to the query of Alibaba 1688, the 16-pin power management chip is the original chip, and the chip model is RT8480, used in charger, control board power supply.
1, EN: Enable foot, usually used to control the start and stop of the chip. CLK: Clock pin, usually used to synchronize the internal operation of the chip. RST: Reset foot, usually used to restore the chip to its initial state. NC: Unconnected pin, usually not connected to any electronic components.
2, reset: used to reset the chip, restore it to the initial state. Reserved: Reserved stitches for future expansion.
3, bidirectional oscillator synchronization function. (4) Voltage mode control or current mode control. 4, specifically, the lithium battery charging chip generally contains a number of pins, which have different functions, such as charging current control, battery voltage detection, temperature detection, and so on. Among them, several common pin functions are as follows: VIN: Input voltage pin, usually connected to the charger power supply, used to provide charging power supply voltage.
5, the transistor has three feet, in the pcb package defines the No. 1 foot, No. 2 foot, no. 3 foot, then the schematic library naturally must also have the rightShould be 3 feet (1-3).
6, d1370001ai integrated block pin function: AMP OUT1 amplified signal output (1). IN1- Anti-trust input (1). IN1 Input (1) with the trust number. GND grounding. As for the Angle voltage, it is not given, because its operating voltage is plus or minus 3 volts to plus or minus 15 volts, so it cannot be given.
TNY280 power chip can not be replaced, you can only buy one.
High performance non-isolated AC-DC conversion chip. Built-in MOS tube withstand voltage 650V, static power consumption 100mW, on-resistance Rds (on) typical value of 15Ω, output 12V/0.3A.
a chip, lm317 chip can be used instead of lm317 can be charged. 220 volts all the way to the clothes.
①, about the above PN8034 chip can not be replaced with PN6012, the reason is that the two chip modelsDifferent, function pins are not available.
This kind of thing is difficult to buy, unless you find the disassembly parts, some new electronic components are not willing to sell, in similar situations, I generally use mobile phone chargers or other power supplies to reform it, so that it outputs the same voltage as electrical appliances, the whole substitute, as far as I know, our circle to do so is very common.
