LM2577 basic properties
 
Module Properties: non-isolated step-up (BO0ST)
Rectification: Non-Synchronous Rectification
Input voltage: 3V-35V
Output voltage: 4-35V
Output Current: 3A (max)
Conversion efficiency: 92% (maximum)
Switching Frequency: 50KHz
Output ripple: 50mV (max)
Load regulation: ± 0.5%
Voltage regulation: ± 0.5%

Product size: 48 * 23 * 14 (L * W * H) (mm)
 
Features:

*After the  LM2577 chip module uses high-quality, high efficiency (up to 92%), while little heat, no increase in the case of the radiator can go to 15W, plus a radiator can go to 25W of output power
*This module uses low-ESR Sanyo original filter capacitor ripple voltage allows low 50mV, can be applied to most applications.

* This module uses machine placement, reflow soldering, and each module shipments have been two hours before the aging tests to ensure high reliability.
 
Applications

* DIY a mobile power supply, only need to take a battery-powered input, you can output 4-35V voltage for your cell phone, MP3, MP4, PSP and many other devices powered charging, very easy oh.
* boost charger, you can charge your device with 4-35V 2 AA batteries or lithium batteries.
* power supply for your electronic devices when your device needs 4-35V power supply when, but you are now the hands of only lithium battery-powered, can boost our module directly to 4-35V, solve your problems.
* pre-supply system, when you do a project when you need to input supply voltage drops below a voltage (4-35V) when, then you choose this module we will be your best choice, no debugging directly on the machine can work, easy to do and efficient high-power boost.

 

 

 

 

If the output power greater than 15W, please add fins

 

Typical efficiency measurements: (24.04V * 1.001A) / (12V * 2.236A) * 100% = 89.6% (not considered line consumption, the actual better)

 

Typical efficiency measurements: (12.24V * 0.501A) / (5V * 1.466A) * 100% = 83.6% (not considered line consumption, the actual better)
