Key Features
- Radiation-tolerant design with SEP qualification makes TPS7H4010MRNPSEP suitable for space and high-reliability satellite power subsystems
- Wide 3.5 V to 32 V input range with current-mode PWM and PFM control enables efficient power conversion across diverse orbital load conditions
- 30-pin QFN package minimizes board area in mass-constrained CubeSat and small satellite power modules
Applications
The TPS7H4010MRNPSEP is engineered for space-grade power subsystems in low-Earth orbit satellites, CubeSats, and high-reliability aerospace platforms where radiation tolerance and single-event protection are mandatory. Its 3.5 V to 32 V input range and current-mode PWM architecture support regulated power conversion for attitude control, payload electronics, and communication modules in harsh radiation environments. The device also suits high-reliability military and avionics power designs that demand radiation-tolerant switching regulators qualified to stringent SEP standards.

Frequently Asked Questions
What radiation tolerance level does TPS7H4010MRNPSEP achieve for satellite power applications?
The TPS7H4010MRNPSEP carries SEP (Single-Event Protection) qualification, making it suitable for low-Earth orbit and deep-space satellite power subsystems subject to energetic particle strikes. It is designed to withstand the heavy-ion and proton environments encountered in orbital applications, with radiation tolerance levels documented in the device's radiation characterization report.
How does TPS7H4010MRNPSEP's PFM mode improve efficiency in satellite power systems at light loads?
In PFM (Pulse Frequency Modulation) mode, the TPS7H4010MRNPSEP reduces switching losses at light loads by decreasing switching frequency, improving efficiency when payloads draw only a fraction of the rated current. This is particularly valuable in satellite power systems with 3.5 V to 32 V input rails where solar panel output varies significantly between sunlit and eclipse phases.
What is the input voltage range of TPS7H4010MRNPSEP, and which power bus standards does it cover?
The TPS7H4010MRNPSEP operates from 3.5 V to 32 V input, covering the 5 V, 12 V, and 28 V satellite bus standards commonly used in small satellite platforms. The 28 V nominal bus used by many spacecraft power distribution units falls well within this operating range, allowing direct connection without pre-regulation.
Is the TPS7H4010MRNPSEP pin-compatible with any commercial TPS7H4010 variant for design migration?
The TPS7H4010MRNPSEP shares the same 30-pin QFN (R-PQCC-N30) footprint as other TPS7H4010 space-grade variants, enabling design reuse between different qualification levels. Engineers can prototype with commercial-grade devices in the same 30-pin package and migrate the same PCB layout to the MRNPSEP space-qualified variant for flight hardware, saving layout iterations and qualification time.
