Описание
80W-1A primary side current loop control LED driver with STCH03 is a demonstration board for street lighting applications with a primary current sensing control loop. The LED driver is a fixed current source with a very fast start-up time, protections to short-circuit and to open load. The board is optimized to supply an LED string load in the range from 40V to 80V with a fixed 1A current source with a very low current ripple. Due to current primary side STCH03 control loop, the output stage is composed of a simple diode rectification and the output capacitor. Form factor is compatible with street lighting application. At full load the efficiency is above the 90% at nominal voltages and remains very close to this value till half the load. Output short-circuit and no-load protections are auto-restart for a safe operation in lighting environment. Low input power is there at no-load conditions.
• Input voltage (Vin) range from 90Vrms to 265Vrms, input frequency range from 45Hz to 66Hz
• LED string range fro 40V to 80V / 1A, output current ripple is < 50mA
• Fast start-up is <300ms, high power factor, low THD (<5%)
• No-load power is < 0.5W at 230Vin
• Average full load efficiency is >90%
• Short circuit protection with auto-restart
• LED string open with auto-restart
• According to EN61000-3-2 class-C or JEITA-MITI class-C
• EMI according to EN55022 class B conducted emissions
• Safety according to EN60065C
