Description:
-- Input voltage: DC 5.5-30V (If input voltage lower than 5V, it can achieve buck/boost, but the measured voltage and current value will be inaccurate. When input voltage lower than 4.7V, it will trigger under-voltage protection).
-- Output voltage: DC 0.5-30V
-- Output current: 4A for long-term working
-- Output power: 35W
-- Voltage display resolution: 0.01V
-- Voltage accuracy: 1%
-- Current display resolution: 0.001A
-- Current accuracy: 1%
-- Conversion efficiency: about 88%
-- Soft start: YES (maybe invalid when starting with high-power load)
-- Working frequency: 180kHz
-- Size: 72*59*32mm
Features:
1. PARAMETER --- buck boost converter, input voltage range 5.5-30V; output voltage range 0.5-30V; working current 4A; power 35W.
2. APPLICATION --- as a normal buck boost converter module with over-current protection; as a battery charger; as a high-power LED constant current driver module, etc.
