三、General Description
The TX9116 Series is a Synchronous step-up DC/DC Converter with PFM Control. With the TX9116 Series, a step-up switching DC/DC converter can be configured by using an external coil, capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged.
