# makanaky ## Description A buck boost converter that can be powered from a Li-Ion battery and output 3.3V @ 500mA. Powered by the TPS63051YFFR and in the same package as a standard Adafruit buck converter. Expect to squeeze around 5-10% SoC from a typical Li-Ion battery. Input Voltage Range: 2.5V to 5.5V ## Project Details - **Owner:** cuv - **Created:** 12/27/2024 - **Last Updated:** 10/21/2025 - **Visibility:** Public ## Key Components ### Q1 — [2N3906](https://www.flux.ai/lcsc/2n3906~ic0w.md) - JLCPCB Part Class: Extended Part - Package or Case Code: TO-92-3_L5.1-W4.1-P1.27-L - Manufacturer Name: ST(先科) - LCSC Part Number: C118539 - Datasheet URL: https://www.lcsc.com/datasheet/lcsc_datasheet_1809192234_ST-Semtech-2N3906_C118539.pdf - Product Info Url: https://lcsc.com/product-detail/Transistors-NPN-PNP_2N3906_C118539.html - Part Type: Bipolar Transistors - BJT - Manufacturer Part Number: 2N3906 **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] ### U1 — [MAX6664AEE+](https://www.flux.ai/lcsc/max6664aeeplus~zvx8.md) - Manufacturer Part Number: MAX6664AEE+ - JLCPCB Part Class: Extended Part - Package or Case Code: QSOP-16_L4.9-W3.9-P0.64-LS6.0-BL-1 - Manufacturer Name: MAXIM(美信) - LCSC Part Number: C1519410 **Pins:** - ~{FAN_FAULT} [pin 8] - ~{INT} [pin 14] - ~{THERM} [pin 7] - ADD [pin 13] - DXN [pin 9] - DXP [pin 10] - GND [pin 5] - N.C.
