Bidirectional PD 100-watt mobile power supply solution based on Yingjixin IP5389-BZ chip design
 
update instructions
1. Optimize wiring and optimize component layout
2. Add TVS absorption board surge      protection main control at the battery interface
     when connected to the battery
The chip and MOS tube will not be broken down by surges (without TVS, there is a chance that the MOS and main control chip will be damaged).
3. The inductor can be replaced with an integrated inductor.
     The inductor can be Sunlord MWSA1206S series 4.7uh to 10uh (for reference only)

the battery pack that supports 2-6 strings
also supports lithium iron phosphate batteries (resistors need to be replaced to set the battery type).
For details, please check the schematic diagram
of an electronic exchange group: 232586710. The chip manual has the highest input and output power
in the group file . For applications
 
up to 100 watts
, you must
pay attention to more than four strings of batteries! ! !
When the board is inputting and outputting high power, the current at the battery terminal is very large. Please pay attention to the battery selection.
The battery is recommended for high-rate battery applications such as Samsung 50E, Samsung 40T, and Lishen LA.
It is recommended that the charging power should not exceed 60 watts.
Applications with 100 watts require at least a four-string-two-parallel structure.
Six-string two-parallel 100-watt applications are available. Battery
boards do not have lithium battery protection and balancing circuits. A protection board with balancing function needs to be used at the battery end.

IP5389 is an integrated QC2.0 / QC3.0 / QC3+ output fast charging protocol, AFC/FCP/ SCP/ VOOC input and output fast charging protocol, USB C PD2.0/PD3. 0 input and output protocol, USB C PD3.0 PPS output protocol, compatible with BC1.2/iPhone, synchronous bidirectional buck-boost converter, lithium battery charging management, battery power indicator and other multi-functional power management SOC, providing fast charging mobile Power supplies provide complete power solutions. It can support four USB ports, USB A .
IP5389's high integration level and rich functions require only one inductor to realize the bidirectional buck-boost function. Only a few peripheral components are needed during application, which effectively reduces the size of the overall solution and reduces the BOM cost.
IP5389 supports 2/3/4/5 cells in series, and the synchronous switching boost and buck system can provide a maximum output capacity of 60W. When no-load, it automatically enters sleep state.
IP5389 synchronous switching charging system provides up to 5.0A charging current. Built-in IC temperature, battery temperature and input voltage control loops intelligently adjust charging current.
IP5389 has a built-in 14bit ADC to accurately measure battery voltage and current. IP5389 has a built-in power calculation method that can accurately obtain battery power information. The battery power curve can be customized to accurately display battery power.
IP5389 supports 4 LED power display, supports 88, 188 and other digital tube power display; supports lighting function; supports buttons.
IP5389 integrates USB C Power Delivery PD2.0/PD3.0/PPS protocol, integrated physical layer protocol (PHY), and hardware bidirectional mark codec (BMC) module.
Supports PD2.0/PD3.0 bidirectional input/output protocol and PPS output protocol. Maximum support for 100W power output, input supports 5V, 9V, 12V, 15V, 20V voltage ranges, output supports 5V, 9V, 12V, 15V, 20V voltage range output broadcast capability 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, PPS 3.3~21V/3A.
 
 
 
 
 
 
 
The following pictures are from the old version.
The board and the panel are connected by soldering.
The bottom can be filled with two layers of 4 mm thick thermally conductive silicone grease pads to conduct heat to the shell.
 
 
The aluminum shell is of customized length (180 mm long), and a battery holder can be added to the battery. .
Taobao stores have mass-produced aluminum shells with a maximum length of 170 mm. If you don’t add a battery holder, you can use a 170 mm long shell.
The length of the battery pack is about 128 mm (different battery lengths will vary), plus the board length is 32 The total mm is 160mm, and there is still a little room left.
The battery needs to be pasted with highland barley paper and EVA foam glue for insulation, buffering and shock absorption.
