5Pcs XL63802 4.2V Lithium Battery USB Auto Buck-Boost Power Supply Module Low Ripple for Microcontroller TPS63802

Product Description

This module adopts the voltage boosting chip TPS63802 voltage boosting scheme, with low output ripple, stable performance, and a switching frequency greater than 1.4MHZ, In most cases, the output current is greater than 1000mA, and there are multiple output versions available, including 3.3V, 4.2V, and 5V, which are very suitable for various 3.3V and 5V single-chip microcontrollers powered by lithium batteries and USB. The module also reserves two modes for users to choose from: high-performance working mode and power-saving/low-power mode. The module is a typical buck boost structure with an input voltage range of 1.3-5 5V (startup requires higher than 1.8V) output current can reach 1A or more, meeting the power supply needs of various models such as STM32, ESP32, 51 microcontroller, etc. It defaults to power-saving mode to increase the battery life of input devices such as batteries. 2、 Parameter Introduction Module type: buck boost power supply Input voltage: DC 1.3-5.5V (starting 1.8V) Output current: [email protected] / [email protected] / [email protected] (3.7V input) Output voltage: DC 3.3/4.2/5V Switching frequency: ≥ 1.4MHZ Working mode: Normal/Power saving mode Static power consumption:<<30uA Adjustment method: jumper pad selection, 3. 3/4.2/5V Module interface: Large area solder pads (can also be connected to 2.54mm pin arrangement) Module size: 12.8 x 25.8mm (manually measured, with deviation)  VIN: Power input positive pole, 1.3-5.5V (starting 1.8V) GND: Input/output negative pole, shared VOUT: Power output terminal, 3. 3/4.2/5V PS: Short circuit pad enables high-performance mode, default disconnect Voltage jumper pad: Short circuiting enables corresponding voltage, and it is prohibited to disconnect or short-circuit multiple at the same time
