Product details
Overview
SSL5001T/1J from NXP Semiconductors is a non-dimmable LED controller IC for flyback and buck-boost topologies driving LED lamps from rectified mains (100–230 V AC). It operates at 66.5 kHz fixed frequency with jitter for EMI reduction, delivers ±10% LED current accuracy, and integrates UVLO, OCP, OTP, OVP, and UVP protection. Used in compact retrofit SSL lamps requiring high efficiency (85% typical) and low BOM count.
For engineers reviewing the SSL5001T/1J datasheet, SSL5001T/1J pinout, SSL5001T/1J application, or SSL5001T/1J equivalent, this page provides verified functional role, validated SO8 package mapping, confirmed 8-pin terminal functions, real-world protection implementation details, and two technically documented alternative controllers for fixed-output LED driver designs.
Technical Context
The SSL5001T/1J implements peak-current-mode control with cycle-by-cycle regulation, enabling low AC mains ripple and no LED current overshoot/undershoot. Its DRIVER pin sources 300 mA and sinks 750 mA to drive an external MOSFET, while SOURCE pin sensing enables precise primary-side current control with 300 ns leading-edge blanking.
It supports mains input detection via VINSENSE (0.94 V start threshold), latched OTP at 140 °C, and hiccup-mode restart via OPTIMER pin discharge (1.2 V restart threshold). Frequency reduction below 66.5 kHz maintains high efficiency at low output power, and overpower compensation uses VINSENSE-to-SOURCE current injection to stabilize output power across 100–230 V AC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC operating range | 14–25 V - powers IC during normal operation; clamped to 22 V during restart |
| fosc | 66.5 kHz typical - fixed switching frequency with ±4 kHz jitter for EMI suppression |
| Driver output capability | 300 mA source / 750 mA sink - ensures fast MOSFET turn-on/turn-off, minimizing conduction losses |
| LED current accuracy | ±10% - achieved via precise internal reference and cycle-by-cycle current control |
| Startup supply current | 10 µA - enables reliable start-up from high-impedance auxiliary winding or startup resistor |
| Thermal shutdown threshold | 140 °C typical - latched OTP halts operation until VCC power cycle resets protection |
| Input voltage sense threshold | 0.94 V on VINSENSE - prevents switching until valid mains presence is confirmed |
Pinout & Package
SSL5001T/1J is housed in an SO8 package (SOT96-1), 3.9 mm body width, surface-mount plastic small outline package with standard 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Supply voltage input | Accepts 14–25 V; internal clamp limits to 22 V during restart; powers all internal circuitry |
| GND (Pin 2) | Ground reference | Common return path for all analog/digital blocks and current-sense reference |

| SOURCE (Pin 4) | Current sense input | Measures primary-side current via external shunt; includes slope compensation and LEB |
| VINSENSE (Pin 5) | Mains voltage detection | Detects rectified AC input level; triggers UVP/OVP when voltage falls below 0.72 V or exceeds 3.52 V |
| PROTECT (Pin 6) | General-purpose fault input | Latched shutdown triggered by voltage <0.5 V or >0.8 V; supports external OTP or OVP circuits |
| CTRL (Pin 7) | Power regulation control | Sets peak current reference; internal 7 kΩ pull-up enables optocoupler feedback for CC/CV operation |
| OPTIMER (Pin 8) | Overpower & restart timer | Charges to 4.5 V on fault; discharges to 1.2 V to enable automatic hiccup-mode restart |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCL30000 | Fixed-frequency flyback controller with similar 65 kHz base frequency but no built-in VINSENSE-based overpower compensation | Requires external circuitry for mains-voltage-dependent power regulation; lacks integrated PROTECT pin logic | Choose for cost-sensitive designs where input voltage range is narrow and external OVP is acceptable |
| Infineon ICE2QS03G | Quasi-resonant controller with variable frequency; higher integration (integrated 650 V MOSFET) but no dedicated PROTECT or VINSENSE pins | Optimized for higher-efficiency CCM operation above 15 W; not suitable for DCM-focused compact lamps | Choose when system-level efficiency >88% is required and board space allows larger QR transformer design |
Compared with NCL30000 and ICE2QS03G, SSL5001T/1J uniquely combines VINSENSE-based overpower compensation, dual-threshold PROTECT pin, and SO8 footprint for retrofit lamp designs demanding minimal component count and robust mains-voltage adaptability.

FAQ
What topology does the SSL5001T/1J support?
The SSL5001T/1J supports both flyback and buck-boost topologies in discontinuous conduction mode (DCM), with design flexibility for continuous conduction mode (CCM) in higher-power implementations. Its peak-current-mode control architecture, combined with VINSENSE and PROTECT pin functionality, enables robust operation across these configurations without requiring topology-specific IC variants. The SSL5001T/1J datasheet confirms compatibility with both structures in Section 8.1 and Figure 3.
Does the SSL5001T/1J require an optocoupler for regulation?
The SSL5001T/1J supports both optocoupler-based and optocoupler-free operation. Constant current regulation can be achieved using primary-side sensing alone, while the CTRL pin allows connection to an optocoupler for constant voltage or tighter constant current performance. This dual-mode capability is explicitly stated in the General Description and Section 8.10, making SSL5001T/1J adaptable to cost- or precision-driven design requirements.
How does the SSL5001T/1J implement overload protection?
The SSL5001T/1J implements overload protection via three coordinated mechanisms: (1) Output short protection (OSP) triggered by abnormal current rise detected at the SOURCE pin, (2) Overtemperature protection (OTP) latched at 140 °C junction temperature, and (3) Mains overvoltage protection (OVP) activated when VINSENSE exceeds 3.52 V. All protections force hiccup-mode restart or latch-off, as detailed in Sections 8.5.3–8.5.5 of the SSL5001T/1J datasheet.
What is the function of the PROTECT pin on the SSL5001T/1J?
The PROTECT pin on the SSL5001T/1J is a general-purpose latched fault input that halts switching when pulled below 0.5 V or above 0.8 V. It sinks or sources microamp-level currents (−32 µA / +107 µA) and features an internal 4.1 V clamp. Per Section 8.5.7, it enables flexible implementation of external overvoltage, overtemperature, or open-circuit detection-distinct from the dedicated VINSENSE and OTP circuits-making SSL5001T/1J highly configurable for custom safety schemes.
Can the SSL5001T/1J operate across 100 V, 120 V, and 230 V AC inputs?
Yes, the SSL5001T/1J is designed for universal operation across 100 V, 120 V, and 230 V AC mains inputs. Its VINSENSE pin monitors input voltage and enables mains overpower compensation (OPC) to maintain near-constant output power across this range. Section 3 of the SSL5001T/1J datasheet explicitly states applicability to all three voltages, with power range determined by external component selection-not by IC variant.
