PWM Controllers Plus LDO Regulators Boost Satellite Performance (Download)

Electronic assemblies headed for space must exhibit minimal size, weight, and power (SWaP) to reduce launch costs and effectively use limited solar-panel or other energy-source outputs. Nevertheless, the circuitry must meet mission requirements for specifications such as data transmission rate, resolution, and sensitivity.

Space-grade pulse-width-modulation (PWM) controllers and low-dropout (LDO) regulators can form the basis for effective space-bound designs, balancing low-noise and high-efficiency performance as required throughout the many subsystems in a modern satellite.
