Description
The LP3208AB5F is a constant frequency, current mode, PWM step-down converter. It integrates a main switch and a synchronous rectifier for high efficiency. With an input voltage range of 2.5V to 5.5V, this component is well-suited for portable electronic devices powered by a 1-cell Li-ion battery or other power sources within the specified range, such as cellular phones, PDAs, and handy-terminals.
One of the key features of the LP3208AB5F is its internal synchronous rectifier with low RDS(ON), which significantly reduces conduction loss in PWM mode. This component also eliminates the need for an external Schottky diode due to its internal synchronous switch, further enhancing efficiency. Additionally, the fixed operation frequency of 1.5MHz allows for easy smoothing of switching ripple using small package filtering elements. The LP3208AB5F's small SOT-23-5 package makes it ideal for applications requiring a small PCB area. Other notable features include soft start, lower internal reference voltage with 2% accuracy, over temperature protection, and over current protection.
