Featured Product ①: RHM4900
Product Summary
The RHM4900 is a 4-channel output, 40V input, 3A (4A peak) step-down Silent Switcher® power μModule® regulator designed for CSL (Commercial Space Low) applications. The Silent Switcher architecture enables highly efficient power conversion at switching frequencies up to 3MHz while minimizing electromagnetic interference (EMI).
The controller, power switch, inductor, and support components are integrated into the package, supporting input voltages from 3V to 40V and output voltages from 0.8V to 8V. Furthermore, by connecting the four outputs in parallel, it can handle up to 12A (16A peak).
Main features

• Supports a wide output voltage range from 0.8V to 8V
• Built-in four 3A (4A peak) step-down switching power supplies
• Employs a low-noise Silent Switcher® architecture.
- Compliant with CISPR22 Class B / CISPR25 Class 5
• Supports switching frequencies up to 3MHz
- Supports increased output current by connecting multiple μModule® units in parallel or using multiphase connections.
• Supports a total dose effect (TID) of up to 75 krad
- No single-event latch-up (SEL) occurred with linear energy transfer (LET) of 40.8 MeV or less at a maximum of 15 VIN.
- Uses a 165-pin, 16mm x 11.9mm x 3.32mm BGA package.
Design advantages
The RHM4900 is a μModule® regulator that integrates key components necessary for power supply circuits into a single package, enabling low-noise, highly integrated power supply designs. It offers the following advantages in power supply designs for space applications:
- It incorporates a controller, power switch, inductor, and support components, reducing the need for external components in the power supply circuit.
The Silent Switcher® architecture enables highly efficient power conversion while suppressing EMI.
• Wide input voltage range of 3V to 40V allows it to accommodate a wide range of input power supply conditions.
It features four 3A (4A peak) outputs, and can be used individually or in parallel to support power configurations of up to 12A (16A peak).
- The output voltage (0.8V to 8V) and switching frequency (200kHz to 3MHz) can each be set with a single resistor, allowing for design tailored to power supply specifications.
- It supports TID up to 75krad and does not generate SEL at LET below 40.8MeV at up to 15VIN, making it suitable for power supply designs that take radiation environments into consideration.
• The main power supply circuit components are integrated into a 16mm x 11.9mm x 3.32mm BGA package, enabling the configuration of a small form factor multi-output power supply.
