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
* Delivery Time.
We need 1-2 days to process your order before shipping.There are two shipping methoed. Fast Delivery: The delivery time for US, European countries the delivery will take 3-5 days.Slow Delivery: The delivery time for US, European countries the delivery will take 10-15 days.
* Tracking information.
After we ship package, customer receive automatic email with tracking details.
* Lost Package Policy.
If a package did not arrive in 4 weeks after the shipping date, then this package is treated as Lost. In this case a new package will be shipped to the customer provided we are able to give the same items as those purchased by the customer. If we are not able to provide the same items to substitute the lost ones we will either propose to the customer similar items or refund their cost as it will be mutually agree with the customer. If one or more items neither the same nor similar are available to be shipped, the customer can request to cancel the order entirely, thus the total cost of the order including shipping and handling cost will be fully refunded.
