IR1110 International Rectifier Corp., IR1110 Datasheet - Page 4

• Manufacturer Part Number: IR1110
• Description: Soft Start Controller Ic In A 64-lead Mqfp Package
• Manufacturer: International Rectifier Corp.

Special Mode of Operation
1. Dedicated single phase operation
For operation with a one-phase bridge, connect 1PHSEL (pin12) to V
ground. Use the SCRU (pin47) and SCRV (pin46) outputs. Use R
0.0068 F 2%.
The following components can be omitted: R
2. Operation without DC bus voltage regulation
For operation without bus voltage, ie. maximum DC bus voltage only, connect VBREF (pin8) to VSS. RERR and CERR can
be omitted. Connect DCREGC (pin10) to ground.

Recommended Operating Conditions cont.
All capacitors are rated 6.3V unless otherwise specified. All resistors are rated 1/16W unless otherwise specified. The
typical connection diagram is shown in figure 3. For proper operation the device should be used with the recommended
componens specified below.

Note 1) Power rating is based on 550VAC rms maximum. For lower AC line voltage, power can be reduced proportionally. Vac
rms max = Maximum operating RMS value of AC line voltage. Use the nearest standard 1% value to calculated value. Resistor
must be rated for peak line voltage.
Note 2) R
Note 3) V
Note 4) With these values LNLED is used for low line detection and is low at line voltage greater than approximately 57% of
Vacrms maximum voltage.
Note 5) Use the nearest standard 1% value to calculated value.
Note 6) C
3.3 F. See Operation Description - Ramp Circuit.
