2 / 2 page Notes: 1. An overtemperature protection circuit shuts down the converter if the temperature at the output inductor exceeds 115°C. The unit will restart automatically when the temperature at the output inductor drops below 110°C. 2. For a 3.3V output, the input range is 4.0 to 5.5 VDC 3. No minimum load is required. Operation at no-load will not damage these units. 4. These converters require no additional external components to meet specifications. However, using external capacitors as shown in the typical connection drawing at right may lower noise in some applications. 5. Transient recovery is measured to within a 1% error band for a load step change of 25% to 100%. 6. It is recommended that a fuse be used on the input of a power supply for protection. Contact the factory for the correct rating.

C1 and C2 are Electrolytic capacitors. C2 should have a low ESR. C3 is a ceramic capacitor. 2. When not being used, the Remote Sense pin (pin 3) should be connected to VOUT as close to the converter as possible. 3. The output voltage of the LR50xxW may be trimmed down by connecting an external resistor between the Trim Pin (pin 4) and Ground (pin 6). This resistor value (in kΩ) is given by: LR5003W-xx RTRIM = 21.07 - 5.11 (VO - 0.7525) LR5012W-xx RTRIM = 10.5 - 1.0 (VO - 0.7525) RTrim values for typical output levels are: Output Voltage LR5003W-xx LR5012W-xx 0.75 VDC Open Open 1.00 VDC 80.021 kΩ 41.424 kΩ 1.20 VDC 41.973 kΩ 22.460 kΩ 1.50 VDC 23.077 kΩ 13.050 kΩ 1.80 VDC 15.004 kΩ 9.024 kΩ 2.00 VDC 11.779 kΩ 7.416 kΩ 2.50 VDC 6.947 kΩ 5.009 kΩ 3.30 VDC 3.160 kΩ 3.122 kΩ 5.00 VDC --- 1.472 kΩ 4. The Control input (pin 11) uses TTL compatible logic as follows: Unit Control Pin ON Open or VIN OFF Grnd or < 0.4V Model Selection Guide Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.01 (±0.25) Mechanical Dimensions Pin Function 1Vin 2 Control 3 Sense 4 Trim 5 Vout 6 Gnd Pin Connections Derating Curve Notes: • All dimens • Tolerance MicroPower Direct www.micropowerdirect.com 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: sales@micropowerdirect.com Typical Connection Diagram |
