STMicroelectronics has added a QML-V certified 7A Level-of-Load (PoL) DC/DC converter to its rising portfolio of radiation-hardened (rad-hard) built-in energy merchandise that ship excessive energy effectivity to fulfill probably the most demanding area purposes.
The RHRPMPOL01 is a whole 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 that has a really low junction-to-case thermal resistance to maximise energy dissipation.
The certified machine, Customary 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 useful interruption (SEFI) are characterised at 7V working voltage. The entire radiation report is accessible upon request.
The RHRPMPOL01 permits each synchronization and present sharing, making it an excellent companion chip to probably the most demanding masses equivalent to FPGAs, microprocessors, and ASICs. The synchronization characteristic permits dephasing a number of PoLs to reduce each the height present of the appliance boards and the output ripple, making certain excessive accuracy. Synchronized gadgets can function with unbiased outputs for masses that require totally different voltage ranges, or with tied outputs to produce high-current masses, on this case leveraging the correct current-sharing performance.
With a excessive absolute most provide score 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% of the enter voltage worth. The 0.8V minimal output permits the converter to supply energy for superior gadgets that function at low provide voltage.
Primarily based on peak-current-mode management, the RHRPMPOL01 is definitely stabilized utilizing exterior parts and ensures quick load-transient response. The switching frequency is programmable from 100kHz to 1MHz, whereas each programmable soft-start period and delay enable designers to restrict the inrush present. An Allow pin simplifies energy sequencing and a Energy-good pin gives real-time data on output-voltage standing.
Leveraging ST’s BCD6s SOI course of know-how, which gives confirmed resilience in opposition to 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 stories. Please contact your native ST workplace for pricing and pattern requests.
