The PW2163 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable ofdelivering 3A current. The PW2163 operates over a wide input voltage range from 4.5V to 18V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 500kHz switching frequency. It adopts the instant PWM architecture to achieve fast transient responsesfor high step down applications

InGaAs/AlGaAs semiconductor lasers come in threetypes: VCSELs and two types of EELs. The VCSEL, asits name implies, emits vertically, normal to the planeof the device, owing to cavity mirrors grown withinthe epitaxial material itself. The VCSEL’s circular beamhas a numerical aperture (NA) of roughly 0.2, or a fullangle of approximately 25 degrees.

The PW2053 is a high-efficiency monolithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provideslow dropout operation, extending battery life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive applications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage

PW1555 is a programmable current limit switch with input voltage range selection and outputvoltage clamping. Extremely low RDS(ON) of the integrated protection N-channel FET helps toreduce power loss during the normal operation. Programmable soft-start time controls the slew rateof the output voltage during the start-up time. Independent enable control allows the complicatedsystem sequencing control. It integrates the over-temperature protection shutdown andautorecovery with hystersis
