Abstract: A method includes generating a drive signal for a transistor in a switching regulator. The drive signal turns the transistor on and off to generate a regulated output voltage. The drive signal is generated based on a clock signal. The method also includes dynamically decreasing a frequency of the clock signal to decrease a dropout voltage of the switching regulator. Dynamically decreasing the frequency of the clock signal can increase a duration of switching periods defined by the clock signal. The dropout voltage could have a first value proportional to TOFF—MIN/TON—MAX during shorter switching periods and a second value proportional to TOFF—MIN/TON—MAX—DFC during longer switching periods. TOFF—MIN represents a minimum amount of off-time for the transistor during each switching period, TON—MAX represents a maximum amount of on-time for the transistor during shorter switching periods, and TON—MAX—DFC represent a maximum amount of on-time for the transistor during longer switching periods.

Abstract: A switching power supply (96) receives an AC voltage and converts it to a regulated DC voltage. The switching power supply (96) includes a Vcc limiter (16) to limit the operating voltage at the power supply terminal (10) of a integrated regulator circuit (118). The Vcc limiter (16) limits the operating voltage at the power supply terminal (10). When operating voltage at power supply terminal (10) increases, a differential pair of transistors (22, 24) supply a differential current to a current mirror configuration of transistors (26, 30) to supply voltage to a drive transistor (36) to increase current in the drive transistor (36) to a value based on n times the current in a reference transistor (26). An increase in current through the drive transistor (36) counteracts increased operating voltage at the power supply terminal (10), thereby reducing the operating voltage level back to a desired level.

A laser diode is positioned in each of the channels and a solder preform, positioned on the top of the laser diode bars. Is heated to flow around each laser diode bar to secure it in place.

Abstract: An array of laser diodes, or laser diode bars, is formed by positioning adjacent diodes or bars in an offset or staircase arrangement where the emitting facets of adjacent diodes, or bars, are in different planes. The offset arrangement permits the light from adjacent facets to be separated a distance q much shorter than permitted by prior art stacking arrangements because thermal and mechanical constraints characteristic of prior art stacks, are relaxed considerably in the offset arrangement. Power densities of 2000 watts/cm.sup.2 (cw) are achieved with spacings of 0.6 mm between adjacent laser bars, a ten fold increase in power density over in-plane (prior art) positioning of like components.
