| Description: Low Noise, Regulated Charge Pump DC/DC Converter 2 in 1 DC-DC Step-Down & Step-Up Converter module Fixed 3.3V+-4% Output Voltage Input Range: 1.8~5V Long time maximum output current 100mA Short time maximum output current 150mA working frequency 1.2MHz. Short-Circuit Protection No load input current : 0.65mA Size 11mm x 7.6mm x 4.5mm(small) Weight : 0.3g(Very very light) The CE021is a low noise, constant frequency (1.2MHz) switched capacitor voltagedoubler. It produce a regulated output voltagefrom a 1.8V to 5V input with up to 100mA of output current.Low external parts count (one flying capacitor and two small bypasscapacitors at VIN and VOUT) make theCE021 ideally suited for small,battery-powered applications. ?? The CE021 have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up. ? High switching frequency enables the use of small ceramic capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1uA. Applications: ? Low Power Wifi Module:ESP8266 Low-power Bluetooth module : HC-05 HC-06 SPP-C Low-power Wireless UART module : HC-11 HC-12 Low-power wireless module : CC1101 CC2500 Nrf24l01+ Low-power LED Driver ? Attention : ? This is a DC-DC voltage converter module,Must be noted when using: 1 Input voltage can not be greater than the maximum input range 2 Output power can not be greater than the maximum load for a long time 3 Input power must be greater than the output power, because the power consumption of the module itself Packing list:5PCS 2 in 1 DC-DC Boost-Buck Charge Pump Converter 1.8V-5V to 3.3V module |
