The Recom Power R-78B9.0-1.0 is a high-efficiency switching regulator from the R-78B-1.0 series, designed as a pin-compatible replacement for 78xx linear regulators. It delivers a regulated 9VDC output at up to 1A from an input voltage range of 12 to 32VDC. With typical efficiency of 95% at minimum input voltage and 93% at maximum input voltage, the device requires no heatsink, saving space and reducing assembly costs.
The converter operates at an internal switching frequency of 280 to 380kHz and features low output ripple and noise of 25 to 35mVp-p. It includes short circuit protection and thermal shutdown for reliable operation. The quiescent current is typically 5mA at a nominal 24VDC input.
The R-78B9.0-1.0 is housed in a compact 3-SIP through-hole package measuring 11.5mm x 8.5mm x 17.5mm. It operates over a temperature range of -40°C to 85°C and requires no minimum load. The device is suitable for ITE (commercial) and medical applications.
