Mini Boost Buck DC Board 1.8-5V to 3.3V, for Battery Juice R2

Description

Use full battery juice!

• Super mini size 11.5×9.5mm, SOT23-6 IC with only three caps
• Input Voltag 1.8-5V, output 3.3V up to 150mA
• Constant Frequency Operation at All Loads. Low Noise Constant Frequency (1.2MHz)
  Operation
• Automatic Soft-Start Reduces Inrush Current
• Shutdown Current <1 uA, No load current is 1.77mA.
• Short-Circuit Protection
• No Inductors
• Standard 2.54 pin output, 3.3V-GND-VIN (face to top), can be used as a normal SMD part.

Testing for reference:

• 1.8V VIN -> 3.3V output
• 1.5V VIN -> 3.1xV output, still can drive a lot MCUs.

Updated to R2:

• Added EN enable pin of the chip
• EN default pull up to high level, connected by jumper VIN.
• Set EN to low level, can simply connect to battery ground to shut power down, for power saving.

Application

• 2 AA Cell to 3.3V, tested can also get 3.2x V from a full 1.5V AA battery.
• USB On-The-Go Devices
• White LED Driver
• Handheld Devices

Each purchase is for one board only.
