ICE3AS02 / ICE3BS02 ICE3AS02G / ICE3BS02G Off-Line SMPS Current Mode Controller with integrated 500V Startup Cell
The ICE3 series are off‑line SMPS current‑mode controllers that integrate a 500 V startup cell and provide active burst mode for ultra‑low standby power. They are offered in DIP‑8 and DSO‑8 packages (PG‑DIP‑8‑6, P‑DSO‑8‑8) and support switching frequencies of 100 kHz or 67 kHz depending on the variant.
Key features include an adjustable blanking window, auto‑restart protection modes, active burst mode for standby power below 100 mW, and a maximum duty cycle of 72 %. The devices operate from a VCC supply of 8.5 V to 21 V and consume as little as 160 µA before activation, dropping to 300 µA in auto‑restart mode.
| Current consumption in Auto Restart Mode | ≈ 300 µA |
|---|---|
| VCC operating voltage range | 8.5 V – 21 V |
| Maximum duty cycle | 72 % |
| Switching frequency (typical) | 100 kHz (ICE3AS02) / 67 kHz (ICE3BS02) |
| Standby power requirement | < 100 mW |
The VCC pin operates between 8.5 V and 21 V.
Standby power consumption is less than 100 mW.
