2 / 2 page Specification Notes: 1. Exceeding 40V on the unit input could damage the unit. 2. No connection should be made between input ground and the output. 3. These are step-down devices, the maximum output open voltage is equal to the input voltage. 4. The PWM/Cont input (Pin 3) should be left open if not used. 5. Exceeding the specified maximum output power could cause damage to the unit. PWM Output Current Control Output current may be adjusted by using a pulse width modulated (PWM) signal. By vary- ing the signal duty cycle (as shown at right) the output current is adjusted up or down. Output current may be calculated by the formula: Where Iout = Required output current Irated = Full rated output current for the unit Dpwm = Duty cycle of the control signal OUT RATED PWM I = I x D Mechanical Dimensions www.micropowerdirect.com MicroPower Direct We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: sales@micropowerdirect.com Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.01 (±0.25) • Pin 1 is marked by a “dot” or indentation on the top of the unit Pin Connections Pin Function 1+VIN +DC Supply 3 PWM PWM, On/Off 4 Gnd -DC Supply 5-VOUT LED Cathode Conn. 6 +Vout LED Anode Conn. Connection Notes: 1. In some noise sensitive applications, the addition of the input filter components (C1, L1 & C2) will help to reduce conducted emissions. 2. Input gnd (Pin 4) cannot be connected to the output. 3. If not being used, the PWM/Control input (Pin 3) should be left open.
