- Excellent efficiency
- Can handle high capacitative loads
RECOM has expanded its range of compact, non-isolated DC-DC power module by launching the RPMB-3.0 series.
Handles high loads
It includes full protection (UVLO, SCP, OCP, OTP) and the ability to drive high capacitive loads up to 0.2F. Power sequencing, soft start, on/off control, remote sensing, and a good signal are also provided.
An evaluation board RPMB-3.0-EVM-1 allows all of these features to be tested with proper component positions for developing an optimum solution that is compliant with class B conducted EMI levels.
Adjustable outputs are 3.3V (trimmable 1-9V), 5V (trimmable 1-9V), 12V (trimmable 9-24V), or 15V (trimmable 9-24V). All variants operate up to 36V input with a low dropout voltage of 500mV or less. They all can operate at a temperature of 100 degrees Celsius, with some load derating, but without needing air cooling. The efficiency is up to 94 per cent that allows the full output current of 3A across the entire input voltage range.
Efficiency is also excellent down to very low loads, which combined with a very low quiescent current of 30µA (3.3V version), makes this series suitable for applications that have ‘sleep’ modes such as microcontrollers and transceivers. The parts also feature 6-sided shielding for low radiated EMI and excellent thermal management.
“The RPMBxx3.0 complements our RPM5.0-3.0 and RPM3.3-3.0 3A-rated switching regulators with its high input voltage rating which includes the industry-standard 24V”, comments Steve Roberts, Innovation Manager at RECOM. “Users can now drop 24V directly to voltages as low as 1V to power sensors, displays, and wireless modules such as GPRS, Wi-Fi, and Bluetooth-meshTM.”
The device is available in standard 12.19 x 12.19 x 3.75mm DOSA-compatible, thermally-enhanced LGA package.
