Typical Application Schematic. Functional Description The LinkSwitch-PL combines a high-voltage power MOSFET switch with a power supply controller in one device. The IC provides a single stage power factor correction plus LED current control. The LinkSwitch-PL controller consists of an oscillator, feedback (sense and logic) circuit, 5.85 V regulator, hysteretic over-temperature protection, frequency jittering, cycle-by-cycle current limit, loop compensation circuitry, autorestart, switching on-time extension, power factor and constant current control. Latching shutdown protection is triggered by a FEEDBACK pin voltage in excess of 2 V. This feature can be used to provide output overvoltage protection (via DZOV and ROV, in Figure 4), which triggers the IC to latch off. This condition is reset when the BYPASS pin voltage drops below 4.9 V, after removal of the AC input. In a direct LED current sensing configuration, the average FEEDBACK pin voltage is a replica of the LED current, scaled by the sense resistor (RSENSE in Figure 4). A small low-pass filter (RF and CF in Figure 4) reduces high frequency noise at the FEEDBACK pin. Latch Off Figure 5 illustrates the operating regions of the FEEDBACK pin voltage. The LinkSwitch-PL sets its operating point such that the average FEEDBACK pin voltage in steady-state operation is 290 mV. This threshold is low to minimize the sensing resistor dissipation. The internal MOSFET switching frequency and on-time are updated once every input AC half-cycle to regulate the output current and maintain high power factor. 2V Cycle Skipping Mode 520 mV If the FEEDBACK pin peak voltage exceeds 520 mV, cycle skipping mode is triggered and the power processed by the integrated MOSFET is clamped on a cycle-by-cycle basis. Switching frequency may vary during an input voltage half-cycle to reduce thermal stress on the output LEDs. Normal Operation 290 mV PI-5838-041910 Figure 5.

Feedback Voltage vs. Phase Angle Dimming Characteristics. TRIAC (Phase-Controlled) Dimming The LinkSwitch-PL integrates several features to improve dimming range and reduce external circuit complexity when using a phase-controlled TRIAC dimmer. The output LED current is controlled by the FEEDBACK pin voltage which changes proportionally to the TRIAC dimmer conduction angle. The conduction angle decreases, the voltage at the FEEDBACK pin decreases causing the average LED current to decrease. The FEEDBACK pin voltage adjustment is initiated at approximately 20% of the main half-cycle duration. When this (jOS) threshold is exceeded, VFB and the output LED current are reduced until a second phase angle threshold is reached. When this happens, with the TRIAC conduction angle being 4 Rev. A 06/10 very limited, the IC runs open loop (j OL region) and the integrated MOSFET processes as much power as the heavily chopped input voltage will allow creating a light output that is deeply dimmed. The 520 mV clamping feedback threshold is also linearly reduced during dimming to control LED current ripple. To help maintain the holding current of the TRIAC in the dimmer, LinkSwitch-PL extends the MOSFET on-time towards the zero crossings of the AC input voltage providing an active bleed or holding current function. This on-time extension is carefully limited to avoid deterioration of input current harmonic content and limit total harmonic distortion (THD). PRELIMINARY This document contains information on a new product. Specifications and information herein are subject to change without notice. www.powerint.com LNK454/456-458/460 IC Supply and BYPASS Pin The internal 5.85 V regulator charges the bypass capacitor connected to the BYPASS pin to 5.85 V by drawing current from the voltage on the DRAIN pin whenever the power MOSFET is off. The BYPASS pin is the internal supply voltage node. When the power MOSFET is on, the device operates from the energy stored in the bypass capacitor. Extremely low power consumption of the internal circuitry allows LinkSwitch-PL to operate continuously from current it takes from the DRAIN pin. A bypass capacitor value of 1 µF is sufficient for both high frequency decoupling and energy storage. Overload Protection In case of overload, the system will increase the operating frequency and on-time each AC half-cycle until the maximum frequency and maximum on-time are reached. When this state is reached, by the next half-cycle, the controller will enter auto-restart protection, thus inhibiting the gate of the power MOSFET for approximately 1.28 s if the main line frequency is 50 Hz, 1.02 s if it is 60 Hz. After this auto-restart off-time expires, the circuit will start again, exactly as at start-up, i.e. at fMIN and tON(MIN), stepping up until regulation is achieved again. In case of a persistent overload condition, the auto-restart duty cycle DCAR will typically be as low as 33%. PR EL IM IN AR Y During phase angle dimming when the conduction angle is small the AC input voltage is present for only short periods of time. In that case the IC should not rely on the integrated high voltage current source, but instead external bias circuitry should be used to supply the IC from the output (DES and RES in Figure 4). If the output voltage is less than 7 V, external bias circuitry should be implemented, by using a bias winding on the primary of the transformer with a small signal rectifier and an electrolytic capacitor with a value based on maximum IC consumption and maximum phase dimming conduction angles. properly designed supply will not operate in this mode under normal load conditions. A power supply designed correctly will operate within the switching frequency range [fMIN … fMAX ], with an on-time falling between tON(MIN) and tON(MAX) when connected to a normal load. Start-up, Switching Frequency, On-time Range At start-up the controller uses an initial switching frequency fMIN and minimum on-time tON(MIN). The charging of the output capacitor together with the energy delivery to the output LEDs as soon as their anode-cathode threshold is reached determines a step-by-step increase of the operating power MOSFET switching frequency and on-time every half-cycle of the main input voltage. When the operating conditions (start-up or large transients) allow for only low energy processing (low frequency and on-time), the voltage across the input bulk capacitance will not reach zero even if the main voltage crosses zero. During these conditions the IC sets the reference voltage on the FEEDBACK pin to one half of its preset level (145 mV), to avoid overshoot of the output LED current. Once the FEEDBACK pin voltage exceeds this reduced threshold (with the zero crossing on the bulk capacitor being achieved), then the FEEDBACK pin voltage is restored to the normal 290 mV level. The steady state switching frequency and on-time is determined by the line voltage, voltage drop across the LEDs and system overall power transfer efficiency. At light load when the device reaches the minimum frequency fMIN and on-time tON(MIN), the controller regulates by skipping cycles. In this mode of operation the input current is not power factor corrected and the average output current is not guaranteed to fall within the normal range. The FEEDBACK pin cycle skipping threshold is reduced from approximately twice the normal regulation level down to just above the level required to limit output power delivery under these conditions. A Auto-restart is inhibited during phase dimming when the TRIAC conduction duty cycle is less than 60%. Output Overvoltage Protection If a no-load condition is present on the output of the supply, the output overvoltage Zener (DZOV in Figure 4) will conduct once its threshold is reached. A voltage VOV in excess of VFB(LO) = 2 V will appear across the FEEDBACK pin and the IC will latch off. Normal operation will be restored once the BYPASS pin voltage drops below 4.9 V and the IC goes through a new start-up phase. Output Short-Circuit If the output of the supply (i.e. the LED load) is short-circuited, then a large amount of energy will be delivered to the sense resistor, generating a high voltage at the FEEDBACK pin. If this condition develops more than 2 V on the FEEDBACK pin, then the IC will interpret this event as an output short-circuit and will trigger latching shutdown. Normal operation will resume after cycling the AC input such that the BYPASS pin voltage drops below 4.9 V and the IC goes through a new start-up phase. Safe Operating Area (SOA) Protection If 3 consecutive cycles of the power MOSFET are prematurely terminated due to the power MOSFET current exceeding the current limit after the leading edge blanking time, SOA protection mode is triggered and the IC will trigger latching shutdown. Normal operation will resume after cycling the AC input such that the BYPASS pin voltage drops below 4.9 V and the IC goes through a new start-up phase. Hysteretic Thermal Shutdown The thermal shutdown circuitry senses the die junction temperature. The thermal shutdown threshold is set to 142 °C typical with a 75 °C hysteresis. When the die temperature rises above this threshold (142 °C) the power MOSFET is disabled and remains disabled until the die temperature falls by 75 °C, at which point the power MOSFET is re-enabled.
