Product details

Overview

ICE3B0365JG from Infineon is a fixed-frequency, 650 V integrated CoolSET™ power controller combining a BiCMOS PWM IC and a depletion-mode CoolMOS™ transistor in a single PG-DSO-12 package. It delivers 10 W output at 85–265 VAC input, operates at 67 kHz with ±5% current limit tolerance, supports Active Burst Mode for <100 mW standby power, and targets offline AC/DC adapters and auxiliary supplies.

For engineers reviewing the ICE3B0365JG datasheet, ICE3B0365JG pinout, ICE3B0365JG application, or ICE3B0365JG equivalent, key selection criteria include its integrated 650 V CoolMOS™, adjustable blanking window via SoftS pin, frequency jittering for EMI reduction, auto-restart protection modes, and minimal external component count for cost-sensitive SMPS designs.

Technical Context

The ICE3B0365JG implements current-mode PWM control with internal leading-edge blanking and propagation delay compensation to maintain stable peak-current limiting across input voltage ranges. Its BiCMOS process enables a wide 10.3–26 V VCC operating range and supports CV/CC secondary-side regulation without auxiliary supply instability.

Active Burst Mode is fully controlled by the FB pin signal and maintains continuous controller activity-enabling immediate load-jump response and <1% output voltage ripple at no load. Protection logic integrates five independent auto-restart triggers: overtemperature, VCC overvoltage, open-loop, overload, and VCC undervoltage.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - Enables direct connection to universal AC mains (85–265 VAC) without pre-regulator
Switching Frequency	67 kHz fixed - Reduces EMI filter size vs. lower frequencies; jittering lowers peak spectral amplitude
R_DS(on)	6.45 Ω @ T_j = 25°C - Sets conduction loss and thermal design margin for 10 W output at 75°C ambient
Max Duty Cycle	75% - Constrains transformer turns ratio and minimum off-time for reliable demagnetization
Current Limit Tolerance	±5% - Enables precise transformer and secondary diode sizing without overdesign
Standby Power	<100 mW @ 270 VAC, no load - Meets Energy Star Level VI and EU CoC Tier 2 requirements
VCC Range	10.3 V to 26 V - Accommodates auxiliary winding variation under CV/CC regulation

Pinout & Package

ICE3B0365JG is housed in a thermally enhanced PG-DSO-12 surface-mount package with exposed drain pads (pins 5–8) for improved heat dissipation and high-voltage isolation.

Pin/Terminal	Circuit Role	Design Meaning
2 (SoftS)	Soft-Start / Blanking Window / Jitter Control	External capacitor sets soft-start ramp time, overload blanking duration, and jitter period-no extra components needed
3 (FB)	Feedback Input	Directly controls duty cycle and Active Burst Mode entry/exit; integrates RC filter previously required externally
4 (CS)	Current Sense Input	Samples source resistor voltage to trigger precise peak-current limiting and enable current-mode control
5–8 (Drain)	Power Switch Drain Terminals	Four paralleled pins reduce R_DS(on) contribution and improve thermal spreading for 650 V CoolMOS™
11 (VCC)	Supply Voltage Input	Accepts 10.3–26 V; internal startup cell draws from Drain during initial charge-eliminates external startup resistor
12 (GND)	Signal Ground Reference	Common return for control circuitry; isolated from power ground in layout to minimize noise coupling

Key Features

Feature	Design Value
Integrated Startup Cell	Connects directly to Drain pin-removes need for external high-voltage startup resistor and reduces light-load losses
Adjustable Blanking Window	Set via SoftS capacitor-delays overload detection during transient load jumps to prevent false tripping
Frequency Jittering	Modulates 67 kHz switching edge timing-lowers EMI peak amplitudes without altering average frequency
Precise Peak Current Limit	±5% tolerance with propagation delay compensation-ensures consistent power delivery across line and temperature
Auto Restart Protection	Five independent fault conditions (OT, OVP, OLP, UVLO, open loop)-resets automatically after fault removal, no manual intervention

Equivalent & Alternatives

The following parts are listed as comparable options for similar AC/DC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICE3B0565JG	Lower R_DS(on) (4.70 Ω), higher output power rating (12 W)	Better suited for 12 W adapters requiring tighter thermal margin at full load	Select when >10 W continuous output or lower conduction loss is required
ICE3BR0665JG	Resonant-mode capable, includes ZVS control, same R_DS(on) and package	Enables quasi-resonant operation for higher efficiency above 50% load	Select when optimizing for full-load efficiency over standby performance

Compared with ICE3B0365JG, ICE3B0565JG offers higher power capability at identical footprint, while ICE3BR0665JG adds resonant control for efficiency gains-neither is pin-compatible but all share PG-DSO-12 layout and feedback architecture.

FAQ

What is the purpose of the SoftS pin in ICE3B0365JG?

The SoftS pin serves three integrated functions: soft-start timing control via external capacitor, adjustable blanking window for high-load transients, and frequency jittering period setting. During startup, it ramps to initiate gate drive; during operation, its voltage level determines burst mode behavior and EMI reduction profile-no additional resistors or diodes are required.

How does Active Burst Mode differ from traditional burst mode in ICE3B0365JG?

Unlike conventional burst modes that disable the controller core, ICE3B0365JG's Active Burst Mode keeps the internal comparator and feedback path continuously active. This ensures immediate response to load steps (<50 ms), maintains output voltage ripple below 1%, and preserves regulation accuracy-critical for systems requiring wake-from-standby responsiveness.

Can ICE3B0365JG operate without an external startup resistor?

Yes. The IC integrates a high-voltage startup cell connected directly to the Drain pin, which charges the VCC capacitor until the 18 V UVLO threshold is reached. Once operational, the startup cell disables automatically-eliminating the external resistor, reducing no-load losses, and improving reliability in high-voltage surge environments.

What protection features are implemented in ICE3B0365JG?

ICE3B0365JG includes five auto-restart protection modes: overtemperature, VCC overvoltage, output open-loop, overload, and VCC undervoltage. Each triggers a controlled shutdown and periodic restart attempt. Recovery occurs automatically once the fault condition clears-no manual reset or AC disconnect is needed, enhancing system robustness in consumer electronics.
