Product details

Overview

ICE3BR2280JZXKLA1 from Infineon Technologies is an integrated off-line SMPS current-mode controller with monolithically embedded 800V avalanche-rugged CoolMOS® and startup cell in PG-DIP-7 package. It delivers 43W max input power at 230VAC ±15%, operates at a fixed 65kHz switching frequency with jitter, and achieves <100mW standby power via Active Burst Mode - used in auxiliary power supplies for PCs, servers, Blu-ray players, and set-top boxes.

For engineers reviewing the ICE3BR2280JZXKLA1 datasheet, ICE3BR2280JZXKLA1 pinout, ICE3BR2280JZXKLA1 application, or ICE3BR2280JZXKLA1 equivalent, key selection criteria include its integrated 800V MOSFET voltage margin, adjustable brownout threshold, selectable burst entry/exit levels, propagation delay compensation for accurate power limiting, and built-in auto-restart protection across overtemperature, overload, VCC OVP/UVP, and open-loop faults.

Technical Context

This IC implements a current-mode PWM controller with BiCMOS process technology enabling 10.5–25V VCC operation and low quiescent current. Its control architecture includes cycle-by-cycle peak current limiting with <±5% tolerance, 10ms built-in soft-start, and patented propagation delay compensation active in both normal and burst modes.

The device integrates a startup cell delivering 0.9mA constant-current charge to CVCC until VCC reaches 17V, then disables itself to eliminate standby loss. Brownout detection, extended blanking (20ms base + external capacitor), and external auto-restart enable (BBA pin) are implemented as single-pin multifunction features with defined voltage thresholds and hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800V - Enables reliable operation under 380VDC input peaks from universal AC mains without derating.
f_SW	65kHz fixed with jitter - Reduces EMI by spreading spectral energy; eliminates need for external oscillator components.
R_DS(on)	2.26Ω @ T_J=25°C - Defines conduction loss in primary-side switch; enables 43W output at 230VAC with minimal heatsink.
Standby Power	<100mW - Achieved via Active Burst Mode; meets Energy Star and EU CoC Tier 2 requirements for auxiliary supplies.
Current Limit Tolerance	<±5% - Ensures consistent overcurrent trip across line/load/temperature; eliminates need for external trimming.
Brownout Hysteresis	Adjustable via external resistor divider - Prevents oscillatory shutdown near AC dropout; supports stable hold-up during brownouts.
OTP Hysteresis	50°C - Provides robust thermal recovery margin after junction temperature exceeds 150°C shutdown threshold.

Pinout & Package

Package: PG-DIP-7 (Plastic Dual-In-Line Package, 7-pin, 0.3" wide, through-hole mount). Pin 6 is omitted per mechanical design; pin 4 is internally not connected.

Pin/Terminal	Circuit Role	Design Meaning
1 - BBA	Brownout / Blanking Extension / Auto-Restart Enable	Multi-function pin: triggers brownout shutdown below ~12V, extends blanking time with external capacitor, forces auto-restart when pulled <0.4V.
2 - FBB	Feedback Input / Burst Entry/Exit Control	Regulates output voltage via optocoupler feedback; sets burst mode transition thresholds via external resistor network.
3 - CS	Current Sense Input	Monitors shunt voltage on CoolMOS® source; initiates immediate gate turn-off at internal 1.0V threshold for cycle-by-cycle protection.
4 - n.c.	No Connection	Internally unconnected; must remain floating - no routing or soldering required.
5 - Drain	CoolMOS® Drain Terminal	Primary-side high-voltage node; connects directly to transformer primary and bulk capacitor positive rail.
7 - VCC	Controller Supply Input	Accepts 10.5–25V DC; powered by startup cell initially, then by auxiliary winding; UVLO threshold = 17V ON / 10.5V OFF.
8 - GND	Power & Signal Reference	Common return for controller logic, gate driver, and current sense amplifier; requires low-inductance layout to CS path.

Key Features

Feature	Design Value
Integrated 800V CoolMOS® with Startup Cell	Eliminates external HV startup resistor and discrete MOSFET; reduces component count by ≥4 and PCB area by >25%.
Active Burst Mode with Selectable Thresholds	Enables user-defined burst entry/exit power levels - supports zero-burst operation for noise-sensitive applications.
Propagation Delay Compensation (Patented)	Maintains consistent peak power limit across 85–265VAC input range - avoids overdesign of transformer and snubber.
Adjustable Brownout Function	Prevents erratic regulation during sustained low-line conditions - improves system reliability in unstable grid environments.
Soft Gate Drive with 50Ω Turn-On Resistor	Reduces EMI and dv/dt stress on transformer insulation; eliminates need for external gate resistor in most designs.

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
ICE3BR1765JZ	650V integrated CoolMOS®, same DIP-7 package, identical pinout, but lower V_DS rating and no brownout adjustability.	Suitable only for 115VAC-only or low-input-voltage designs; lacks brownout hysteresis and burst-level selectability.	Select when cost sensitivity outweighs universal input requirement and brownout resilience is non-critical.
ICE5QSBG	800V CoolMOS® + controller in DSOF-8 package; supports QR/CCM/DCM modes; higher integration (no external CS resistor needed); 65kHz fixed frequency.	Requires different PCB layout and transformer design due to surface-mount package and valley-switching operation.	Choose for new designs targeting higher efficiency (>88%) and smaller form factor where requalification effort is acceptable.

Compared with ICE3BR1765JZ and ICE5QSBG, ICE3BR2280JZXKLA1 uniquely balances universal-input ruggedness (800V), through-hole manufacturability (DIP-7), and field-deployable reliability features (adjustable brownout, selectable burst, 50°C OTP hysteresis) - making it optimal for cost-constrained, high-volume auxiliary supplies requiring long-term supply stability.

FAQ

What is the purpose of the BBA pin on ICE3BR2280JZXKLA1?

The BBA pin serves three distinct functions: brownout detection (shuts down switching below configurable input voltage), extension of the 20ms blanking time for overload protection (via external capacitor to ground), and external forcing of auto-restart mode (when pulled below 0.4V). All functions share the same pin but operate independently based on voltage thresholds and timing conditions defined in the datasheet.

Does ICE3BR2280JZXKLA1 require an external current-sense resistor?

No - the device senses current directly through the source terminal of its integrated CoolMOS® via the CS pin. An external shunt resistor is still required between the CoolMOS® source and power ground to develop the sensing voltage; however, no additional current-sense amplifier or resistor-to-VCC connection is needed, as the CS comparator and reference are fully internal.

How does the Active Burst Mode reduce standby power below 100mW?

During light load, the controller enters Active Burst Mode by pausing switching cycles entirely and only resuming brief bursts when output voltage droop exceeds a user-set threshold via the FBB pin. This eliminates switching losses and minimizes gate drive current, while the BiCMOS process ensures ultra-low quiescent current (<1mA) in burst state - collectively achieving <100mW total input power at no load.

Can ICE3BR2280JZXKLA1 be used in 115VAC-only applications?

Yes - although optimized for universal input (85–265VAC), its 800V CoolMOS® provides ample voltage margin at 115VAC. Designers may simplify the front-end rectifier and bulk capacitor selection, and optionally disable brownout or reduce its threshold. The fixed 65kHz frequency and integrated protections remain fully functional regardless of input voltage range.
