Specifi cations subject to change without notice.
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 specifi cations. 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. Model Number Input Output Voltage (VDC) Voltage (VDC) Current (A, Max)Nominal Range 1. C 1 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 SR50xxW may be trimmed down by connecting an external resistor between the Trim Pin (pin 10) and Ground (pins 5 & 6). This resistor value (in kΩ) is given by: SR5003W-xx RTRIM = 21.07 - 5.11 (VO - 0.7525) SR5012W-xx RTRIM = 10.5 - 1.0 (VO - 0.7525) R Trim values for typical output levels are: Output Voltage SR5003W-xx SR5012W-xx
