RECOM Power RVB019 Current-Mode Buck Converters

RECOM Power RVB019 Current-Mode Buck Converters are current-mode power converters that integrate the control circuitry and power MOSFET on a single die using advanced BCD process technology. These converters feature a 5V to 40V input voltage range, 2A continuous output current, 500µA quiescent operating current, an integrated high-side 0.1Ω LDMOS, and a minimum on-time of 100ns. The RVB019 converters integrate multiple control functions and require only minimal external components, allowing peripheral parameters to be flexibly configured to meet application requirements. These converters offer peak current-mode control, integrated loop compensation, and up to 1MHz operating frequency. Typical applications include PoE power supplies, electric bicycles, industrial power conversion, auxiliary power supply for BMS, automotive battery voltage regulation, telecommunications, and data communications.

The RVB019 buck converters are available in an ESOP8 package with enhanced thermal performance. Protection features include cycle-by-cycle overcurrent protection, output short-circuit protection, overtemperature protection, and input Undervoltage Lockout (UVLO). All protection mechanisms support automatic recovery once abnormal conditions are removed, maximizing the reliability of the switching power supply system.
