Overview
RP506x Series 2 A PWM/VFM Step-down DC/DC Converter with Synchronous Rectifier NO.
EA-296-130925 OUTLINE The RP506x are low supply current CMOS-based PWM/VFM step-down DC/DC converters with synchronous rectifier featuring 2 A*1 output current.
Internally, a single converter consists of an oscillator, a reference voltage unit, an error amplifier, a switching control circuit, a mode control circuit, a soft start circuit, a latch type protection circuit, an under-voltage lockout (UVLO) circuit, a thermal shutdown circuit, and switching transistors.
The RP5 06x is empl oying synchronous rectification f or imp roving the efficiency of rectificatio n by repla cing diodes with built-in switching transistors.
Using synchronous rectification not only increases circuit performance but also allows a design to reduce parts count.
Power controlling method can be selected from forced PWM control type or PWM/VFM auto switching control type by inputting a signal to the MODE pin.
In low output current, ...
