DC/DC Converter IC for Charging Li-ion Battery
- DESCRIPTION
MB39A113 is a DC/DC converter IC of pulse width modulation (PWM) type for charging, capable of independently controlling the output voltage and output current. MB39A113 is suitable for down conversion. MB39A113 can dynamically control the charge current of the secondary battery, to keep the power constant by detecting a voltage drop in an AC adapter (dynamically-controlled charging) . MB39A113 can easily set the charge current value, making it ideal for use as a built-in charging device in products such as...
