TPS61088 demo board

1. Module Introduction
The low-power DCDC boost module built based on the TPS61088 chip
supports wide voltage input and
the maximum power can reach 15W (single channel)
 
2. Application scenarios
battery power supply system, mobile power
boost module
 
3. Module overview
This module uses the TPS61088 chip The design
is compatible with a wide range of input voltage (cannot exceed the maximum withstand voltage of the chip).
An additional circuit is reserved for parallel function verification.
This module has over-current protection and under-voltage shutdown protection.
This chip has excellent load step response. Capability, low ripple
 
, module parameters

Peak current mode (cycle-by-cycle overcurrent protection)
Built-in MOS tube, synchronous rectification architecture
FB reference voltage: 1.2V
Compensation network model: Adjustable transconductance
switching frequency: 200K- 2.2MHz
with current limit function
suitable for battery-powered low-power products
 
Module PCB size 80*41mm
Module design voltage input range 3-9V
Module maximum output voltage 12V
Module maximum output current 10A (output voltage needs to be considered)
Module maximum output power 30W (maximum 15W per channel, actual heat dissipation needs to be taken into consideration)
The maximum efficiency can reach 90% (actual measurement data)
 
5. Instructions for use
Connect the 3-9V power supply (can be a lithium battery) to the input terminal on the left and the terminal on the right It is an output terminal block that can be connected to an electronic load or other load.
After powering on, you should use a multimeter to test whether the output voltage reaches the design value. If it does not reach the design value, do not connect the load to the input
positive and negative poles. Do not connect the positive and negative poles reversely, which may damage the module.
The output voltage is fixed. If you need to change the output voltage, you need to adjust the ratio of the upper and lower resistors of FB.
 
6. Precautions and Remarks
: It is recommended to use a current within 3A for long-term work (you need to pay attention to the temperature rise)
because it is a Boost topology. , in order to work properly, a certain voltage difference needs to be maintained (recommended to be greater than 1V)
