NISSHINBO Launched 0.5A/1A 6MHz PWM/VFM Step-down DC/DC Converter RP539 Series with Synchronous Rectifier
The RP539 Series is a low-supply current CMOS-based PWM/VFM Step-down DC/DC Converter with a synchronous rectifier featuring 0.5A/1A output current. Internally, a single converter consists of a reference voltage unit, an error amplifier, a switching control circuit, a mode control circuit, a soft-start circuit, an under-voltage lockout (UVLO) circuit, a thermal shutdown circuit, and switching transistors. The RP539 Series is employing synchronous rectification for improving the efficiency of rectification by replacing diodes with built-in switching transistors.
Using synchronous rectification not only increases circuit performance but also allows a design to reduce parts count. The output voltage controlling method is selectable between a PWM/VFM auto-switching control type and a forced PWM control type, which further reduces noise than a normal PWM control under a light load, and these types can be set by the MODE pin. Output voltage type is selectable between an internally fixed output voltage type and an externally adjustable output voltage type. Protection circuits in the RP539 Series are the current limit circuit and thermal shutdown circuit. LX's current limit value (Typ.) is selectable between 1.6A and 1.0A.
The RP539Z is available in WLCSP-6-P6 which achieves high-density mounting on boards. Using a capacitor of 0402-/1005-size (inch/mm) and an inductor of 0402-/1005-size (inch/mm) as external parts help to save space for devices.
