The system is area certified and is provided with excessive absolute most provide ranking for larger effectivity

This QML-V certified 7A Level-of-Load (PoL) DC-DC converter enhances the vary of radiation-hardened (rad-hard) built-in energy merchandise that ship excessive energy effectivity to fulfill probably the most demanding area functions.

The RHRPMPOL01 is an entire PoL converter, together with N-channel energy MOSFET and bootstrap diode, with under-voltage, over-voltage, over-temperature and adjustable over-current safety in a compact Energy FLAT-28A hermetically sealed ceramic bundle, which has a low junction-to-case thermal resistance that maximises energy dissipation.

The certified system, Normal Microcircuit Drawing (SMD) 5962-28208, is Radiation Hardness Assured (RHA) as much as 100krad(Si), and Single Occasion Latch-up (SEL) and Single Occasion Snap-Again (SESB) free as much as 70Mev.cm2/mq. Single-event upset (SEU) and single-event practical interruption (SEFI) are characterised at 7V working voltage. 

Ultimate for demanding hundreds

The RHRPMPOL01 permits each synchronisation and present sharing, making it an excellent companion chip to probably the most demanding hundreds comparable to FPGAs, microprocessors and ASICs. The synchronisation characteristic permits dephasing a number of PoLs to minimise each the height present of the applying boards and the output ripple, guaranteeing excessive accuracy. Synchronised units can function with impartial outputs for hundreds that require completely different voltage ranges or with tied outputs to provide high-current hundreds

With a excessive absolute most provide ranking of 14V, the RHRPMPOL01 converts an enter voltage within the vary 3.0V to 12V to an output voltage that may be set from 0.8V to 85 per cent of the enter voltage worth. The 0.8V minimal output permits the converter to supply energy for superior units that function at low provide voltage.

Simplified energy sequencing

Based mostly on peak-current-mode management, the RHRPMPOL01 is well stabilised utilizing exterior parts and ensures quick load-transient response. The switching frequency is programmable from 100kHz to 1MHz, whereas each programmable soft-start length and delay permit designers to restrict the inrush present. An Allow pin simplifies energy sequencing and a Energy-good pin gives real-time data on the output-voltage standing.

Leveraging ST’s BCD6s SOI course of expertise, which gives confirmed resilience towards single-event results, the RHRPMPOL1 has been developed with the assist of the European Area Company (ESA) and the French Authorities Area Company, CNES.

The RHRPMPOL01 is in manufacturing now and is supported by a complete ecosystem that features the EVAL-RHRPMPOL01 analysis board and consumer information, PSpice fashions, and documentation together with radiation reviews. They are often obtained from STMicroelectronics.
