Cooling Method

Free-air convection

1.All specifications valid at normal input voltage, full load and +25°C after warm-up time unless otherwise stated.

2.Ripple & Noise are measured at 20MHz of bandwidth with 0.1uF & 47uF parallel capacitor.

OUTPUT NOISE

The output noise is measured with 10

μF tantalum capacitor and 0.1μF ceramic capacitor across output.
