POLs

Teledyne HiRel’s Point-of-Load power products follow a tradition of high performance and efficiency. The original power management family provides three different load configurations and supports DC to DC conversion with radiation-tolerant point-of-load (POL) synchronous buck regulators with integrated switches. These devices offer SEE immunity to a linear energy transfer (LET) greater than 90 MeV.cm2/mg and TID of 100 kRad(Si). By offering superior performance, smaller size and reduced weight, these monolithic power management products can replace multi-chip modules in sensitive space applications.

DC-DC converters from Teledyne HiRel are the industry’s smallest, space-grade, monolithic non-isolated distributed power solutions. They can replace traditional multi-chip modules that power field-programmable gate array (FPGA), digital signal processor (DSP), ASIC and SRAM power management designs. The combination of small size, high levels of integration and efficiency lowers total system weight and associated costs. Teledyne HiRel’s converters are designed to operate from a wide bus rail and provide output voltage supply rails for analog, digital and RF payloads while delivering continuous output current. The converters also achieve high peak efficiency of 93+ percent through monolithic integration that reduces switch loss. The components feature an external resistor that provides adjustable slope compensation to optimize closed-loop bandwidth across output voltage and switching frequency range.

Teledyne HiRel’s DC-DC converters are radiation-hardened and immune from single event latch-ups (SELs), making them ideal for space applications. They are also optimized for defense and commercial applications, such as satellite systems, military radios, radar, engine control modules (ECMs), down-hole drilling and other high-reliability systems.
