Product details
Overview
ICE3DS01L from Infineon Technologies is an off-line AC/DC current-mode PWM controller IC with integrated 500 V startup cell, fixed 110 kHz switching frequency, ±5% peak current limit tolerance, and active burst mode enabling <100 mW standby power in universal-input (85–270 VAC) SMPS for consumer adapters and auxiliary supplies.
For engineers reviewing the ICE3DS01L datasheet, ICE3DS01L pinout, ICE3DS01L application, or ICE3DS01L equivalent, key selection considerations include its latched-off protection behavior under overtemperature/overvoltage, internal leading-edge blanking (220 ns), soft-driving gate output for low EMI, and dual-package availability (PG-DIP-8-6 and PG-DSO-8-8).
Technical Context
The ICE3DS01L implements a current-mode control architecture with an internal oscillator fixed at 110 kHz, precise peak-current sensing via CS input with propagation-delay compensation, and a dedicated HV pin feeding a self-biasing 500 V startup cell that disables automatically once VCC reaches 15 V. Its PWM latch (FF1) and soft-driver stage ensure stable duty-cycle control up to 72% max.
Control logic integrates three distinct fault-handling modes: latched-off mode (non-self-recovering, requires AC disconnect) for overtemperature (>140°C), overvoltage, or short-winding faults; auto-restart mode for overload/open-loop/VCC undervoltage (<6 V); and active burst mode triggered by FB signal at light load, maintaining regulation with <1% output ripple while minimizing switching losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 110 kHz fixed - eliminates external timing components and ensures EMI compliance in compact adapter designs. |
| Peak Current Limit Tolerance | ±5% overall - enables accurate transformer sizing and consistent power delivery across line/load variations. |
| Startup Voltage Range | 500 V HV-rated startup cell - removes need for external high-voltage resistor, reducing BOM count and leakage losses. |
| Max Duty Cycle | 72% - supports wide input range operation while maintaining safe MOSFET conduction margins. |
| Standby Power | <100 mW at no load - meets stringent global energy efficiency standards (e.g., Energy Star, ERP Tier 2) without auxiliary winding. |
| Leading Edge Blanking | 220 ns internal - suppresses false current-sense triggering during MOSFET turn-on spikes, improving reliability under transient loads. |
| VCC Operating Range | 8.5 V to 21 V - accommodates wide auxiliary supply variation while supporting brown-out recovery and robust restart behavior. |
Pinout & Package
ICE3DS01L is available in two RoHS-compliant packages: PG-DIP-8-6 (through-hole) and PG-DSO-8-8 (surface-mount). Pin 4 and 5 are internally shorted in PG-DIP-8-6; PG-DSO-8-8 includes a dedicated N.C. pin (Pin 6) and separates HV and Gate functions across distinct pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SoftS | Soft-start & blanking window control | External capacitor sets soft-start time and disables overload detection during high-load transients (adjustable blanking window). |
| FB | Feedback input | Regulates output voltage via optocoupler; directly controls active burst mode entry/exit and PWM duty cycle. |
| CS | Current sense input | Monitors source resistor voltage; triggers immediate gate shutdown at 0.85 V threshold with propagation-delay compensation. |
| HV | High-voltage startup input | Connects to rectified DC bus; powers internal 500 V startup cell until VCC reaches 15 V, then disables automatically. |
| Gate | Power MOSFET driver output | Low-impedance totem-pole output drives external MOSFET gate with soft-switching profile to reduce EMI. |
| VCC | Controller supply rail | Powered by auxiliary winding; UVLO activates at 8.5 V (off) and 15 V (on); operating range 8.5–21 V. |
| GND | Signal reference ground | Common return for internal bias, feedback, and current sense circuits; must be separated from power ground in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Active Burst Mode | Enables continuous regulation at light load with <100 mW standby power and immediate response to load jumps-no output blackout. |
| Latched Off Mode | Non-recoverable shutdown on overtemperature (>140°C), overvoltage, or short-winding fault-requires AC disconnect to reset. |
| Integrated Startup Cell | 500 V-rated HV input eliminates external startup resistor, reducing component count and improving light-load efficiency. |
| Adjustable Blanking Window | Configured via SoftS capacitor to disable overload detection during high di/dt events-prevents false triggering of auto-restart. |
| Precision Current Limiting | ±5% total tolerance with propagation-delay compensation ensures consistent power limiting across input voltage range (85–270 VAC). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line current-mode SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE3B0565J | Fixed 65 kHz frequency, no integrated HV startup cell, requires external startup resistor. | Lacks active burst mode; standby power typically >250 mW-unsuitable for strict no-load regulations. | Select when cost sensitivity outweighs standby efficiency and thermal safety is less critical. |
| LD7575P | Variable frequency (60–100 kHz), no latched-off mode, only auto-restart protection. | No thermal latch-off; relies on external NTC for overtemperature-increases design complexity and failure risk. | Prefer for legacy designs where burst mode is unnecessary and thermal monitoring is handled externally. |
Compared with ICE3B0565J and LD7575P, ICE3DS01L delivers superior no-load efficiency, intrinsic thermal safety via junction-sensed latched-off mode, and reduced BOM count through integrated HV startup-making it optimal for next-generation energy-compliant adapters and industrial auxiliary supplies.

FAQ
What is the purpose of the SoftS pin beyond soft-start?
The SoftS pin serves three confirmed functions: (1) sets soft-start time via external capacitor; (2) configures the adjustable blanking window duration to suppress false overload detection during high di/dt load jumps; and (3) controls auto-restart timing after fault clearance. Its voltage level directly modulates burst-mode frequency and blanking window width per datasheet Section 1.3 and Figure 3 block diagram.
How does the 500 V startup cell improve system efficiency?
The integrated 500 V startup cell draws 1.05 mA from the HV pin to charge the VCC capacitor until the UVLO threshold (15 V) is reached, then switches off completely. This eliminates continuous power loss from an external high-voltage resistor-reducing no-load dissipation by ~150 mW in typical 12 V/1 A auxiliary supplies, directly enabling sub-100 mW standby compliance.
What triggers latched-off mode versus auto-restart mode?
Latched-off mode activates for catastrophic faults: junction temperature >140°C (thermal shutdown), output overvoltage >6.5 V (via FB comparator), or primary winding short (via CS overcurrent with extended timeout). Auto-restart mode handles recoverable faults: VCC undervoltage (<6 V), open-loop regulation, or sustained overload-cycling at ~1 Hz until fault clears, per Section 3.6.3 of the datasheet.
Can ICE3DS01L operate without an auxiliary winding?
No-ICE3DS01L requires an auxiliary winding to supply VCC after startup. The integrated HV startup cell only charges VCC during initial power-up; once VCC exceeds 15 V, the startup cell disables and the IC relies entirely on the auxiliary winding for continuous operation. Omitting the auxiliary winding causes immediate VCC dropout and latch-off after startup.
