The Premium NP-0606 is a high‑efficiency DC/DC power supply module that delivers a regulated 26 V output at up to 6 A. It is designed for board‑mount applications within ASML equipment, identified by the ASML material number 4022.476.01341. This module is ideal for powering control circuits, motor drives, and communication interfaces that require a stable, low‑noise voltage source.
Input Voltage Range: 18 – 36 V DC (nominal 24 V)
Output Voltage: 26 V DC ±1 %, adjustable ±5 %
Output Current: 6 A continuous, 7.5 A peak (for 1 s)
Output Ripple: < 50 mV peak‑to‑peak (20 MHz BW)
Efficiency: 94 % at full load (24 V input)
Line Regulation: ±0.2 %
Load Regulation: ±0.5 % (0‑100 % load)
Switching Frequency: 500 kHz
The NP-0606 includes comprehensive protection: input undervoltage lockout, output overvoltage clamp (30 V), overcurrent limiting with hiccup mode, and overtemperature shutdown (at 110 °C case temperature). A power‑good signal (open‑collector) is provided to indicate that the output is within regulation. The module also has a remote sense feature to compensate for voltage drops in the load wiring.
The module is encapsulated in a thermally conductive epoxy and measures 50.8 mm x 40.6 mm x 12.7 mm (2” x 1.6” x 0.5”). It has 8 pins with a standard 2.54 mm pitch. Operating temperature range is –40 °C to +85 °C; derating is required above 70 °C (reduce output current by 0.1 A per °C). The module is designed for convection cooling but can be mounted on a heatsink for higher ambient temperatures.
This power supply is used in various ASML subsystems where a 26 V rail is needed, for example, to power the wafer stage linear encoders or the reticle scanning motors. Its low ripple ensures accurate encoder readings, while the high efficiency reduces heat dissipation in crowded chassis. The module is often placed on a mid‑plane PCB that distributes power to multiple peripheral cards.
The NP-0606 is a through‑hole module; solder it to the PCB using standard wave‑soldering or hand‑soldering techniques. Ensure that the input and output capacitors (recommended: 100 µF electrolytic + 1 µF ceramic) are placed close to the module pins to minimize ringing. The remote sense pins should be connected to the load points directly, using twisted pairs to avoid noise pick‑up.
Each module is tested at the factory for output voltage accuracy, load regulation, and ripple. A test report is included with each shipment. For field validation, check the output voltage under load and verify that the power‑good signal goes high within 10 ms of input application. If the module fails, replacement is straightforward; no calibration is required after replacement.
