Product details
Overview
ICE3B0365J-T from Infineon Technologies is an integrated off-line SMPS current-mode controller with a built-in 650V CoolMOS® power transistor and startup cell in PG-DIP-8 package, operating at 67 kHz fixed frequency with frequency jittering for EMI reduction, ±5% peak current limit tolerance, and active burst mode enabling <100 mW standby power - used in low-cost AC/DC adapters and auxiliary power supplies.
For engineers reviewing the ICE3B0365J-T datasheet, ICE3B0365J-T pinout, ICE3B0365J-T application, or ICE3B0365J-T equivalent, this device delivers verified primary-side regulation for universal-input (85–265 VAC) flyback converters requiring high reliability under load jumps, auto-restart protection, and minimal external component count.
Technical Context
The ICE3B0365J-T implements BiCMOS-based current-mode PWM control with internal oscillator, precise leading-edge blanking, and propagation delay compensation to maintain stable power limiting across input voltage variations. Its integrated 650V CoolMOS® enables direct high-voltage drain connection without external startup resistor.
It features dual-function SoftS pin controlling soft-start timing, adjustable blanking window for overload immunity, and frequency jitter period - all set by a single external capacitor. The FB pin accepts optocoupler feedback for CV/CC regulation while enabling seamless transition into active burst mode below ~3.0 V.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SoftS | Soft-start timing, blanking window adjustment, frequency jitter control, and auto-restart trigger - set by external capacitor to GND |
| 2 | FB | Feedback input for optocoupler-based regulation; controls duty cycle and triggers Active Burst Mode when voltage drops below ~3.0 V |
| 3 | CS | Current sense input tied to CoolMOS® source; detects primary current for cycle-by-cycle limiting and PWM slope compensation |
| 4 & 5 | Drain | Common high-voltage drain node of integrated 650V CoolMOS®; connects directly to rectified AC line or transformer primary |
| 6 | N.C. | No internal connection; must remain unconnected per datasheet |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller with integrated HV MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B0365G-T | No frequency jittering; fixed 67 kHz only; identical pinout and protection features | Lacks EMI reduction benefit; suitable where conducted emissions testing passes without jitter | Select when EMI filtering budget is available or regulatory limits are less stringent |
| ICE3BR0665JZ | Same jitter function but includes Brown-Out Protection (BOP) and higher VCC max (30 V); DIP-7 package with Drain and Source pins combined | Supports wider auxiliary supply range and adds brown-out detection for unstable grid regions | Prefer for deployments in emerging markets with frequent voltage sags or where space permits DIP-7 layout |
Compared with ICE3B0365G-T, the ICE3B0365J-T provides measurable EMI reduction without design changes; versus ICE3BR0665JZ, it trades brown-out protection and higher VCC headroom for DIP-8 compatibility and proven thermal performance in legacy adapter footprints.

FAQ
What is the purpose of the SoftS pin beyond soft-start?
The SoftS pin serves three critical functions: it sets soft-start duration via external capacitor, defines the adjustable blanking window to prevent false overcurrent shutdown during fast load transients, and controls the frequency jitter period to reduce EMI peaks - all using a single capacitor to ground, simplifying layout and reducing part count.
Does ICE3B0365J-T require an external startup resistor?
No. The integrated startup cell draws 1.05 mA from the Drain pin to charge the VCC capacitor during initial power-up, eliminating the need for an external high-voltage startup resistor - reducing power loss, component count, and PCB area while improving light-load efficiency.
How does Active Burst Mode differ from traditional burst mode?
Unlike conventional burst modes that disable the controller between bursts (causing output voltage droop and delayed load response), ICE3B0365J-T's Active Burst Mode keeps the control circuitry fully operational - enabling immediate duty-cycle adjustment upon load change and maintaining output ripple below 1% without blackouts or regulation lag.
Can ICE3B0365J-T be used in continuous conduction mode (CCM) flyback designs?
Yes - its 75% maximum duty cycle, precise current sensing, and propagation delay compensation support both discontinuous (DCM) and continuous conduction mode (CCM) flyback operation; however, CCM designs require careful transformer design to avoid saturation and ensure stable current-mode control across full input voltage range.
