RP601 Series
1A PWM/VFM Step-up/down DCDC Converter with Synchronous Rectifier
- PLP
- RoHS
Product Specifications
The RP601 Series are CMOS-based PWM/VFM step-up/down DC/DC converters with synchronous rectifier. The RP601 automatically switches between step-up mode and step-down mode according to input voltage, output voltage and load current. The 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. The forced bypass mode (PWM/VFM auto switching control, BP pin = H) is included which suppresses supply current below 5 µA. The output voltage is adjustable (50-mV step) using DVS (Dynamic Voltage Scaling) during operation. A 1.95-mm square compact WLCSP-16-P1 package is available.
