nxp公司的ssl21084 是greenchip led照明驱动器,输入电压230vac,效率高达95%,驱动器集成了600v功率mosfet,具有欠压保护(uvlo),前沿消隐(leb),过流保护(ocp),绕组短路保护(swp)以及超温保护(otp),主要用在led照明.本文介绍了ssl2108x系列主要特性格和优势,方框图, 基本应用电路图, 降压转换器配置图以及ssl21084参考板主要指标,电路图,材料清单和pcb布局图.
the ssl2108x is a range of high-voltage integrated circuits (ics), intended to drive led lamps in general lighting applications.
the main benefits of the product family are:
•small printed-circuit board (pcb) footprint, and compact solution
•high efficiency (up to 95 %)
•ease of integration
•low electronic bill of material (bom)
the product family is made of ics with a range of internal hv switches for easy power scaling.
the ics work as boundary conduction mode converters, typically in buck configuration. the ic range has been designed to start up directly from the hv supply by an internal high-voltage current source. thereafter, the dv/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. this functionality provides full flexibility in the application design. the ic consumes 1.3 ma of supply current with an internal clamp limiting the supply voltage.
the ics provide accurate output current control with led current accuracy within 5%. the ics can be operated using pulse-width modulation (pwm) dimming and has many protection features including easy led temperature feedback.
ssl2108x系列主要特性格和优势:
led driver ic family driving strings of leds from a rectified mains supply
high-efficiency switch mode buck driver product family:
drivers with integrated 300 v (ssl21081 and ssl21082) or 600 v (ssl21083 and ssl21084) power switches
controller with power-efficient boundary conduction mode of operation with:
no reverse recovery losses in freewheel diode
zero current switching (zcs) for turn-on of switch
zero voltage or valley switching for turn-on of switch
minimal required inductance value and size
direct pwm dimming possible
fast transient response through cycle-by-cycle current control:
negligible ac mains ripple at led current and minimal total capacitor value
no over or undershoots in the led current
no binning on led forward voltage required
internal protections:
undervoltage lockout (uvlo)
leading-edge blanking (leb)
overcurrent protection (ocp)
short-winding protection (swp)
internal overtemperature protection (otp)
brownout protection
output short protection (osp)
low component count (see figure 4) led driver solution:
no schottky diode required due to zcs
no dim switch and high-side driver required for pwm dimming
easy external temperature protection with a single ntc resistor
option for soft-start function
compatible with wall switches with built-in indication light during standby1
ic lifetime easily matches or surpasses led lamp lifetime
ssl2108x系列应用:
ssl2108x products are intended for compact led lighting applications with accurate fixed current output for single mains input voltages. mains input voltages include 100 v, 120 v and 230 v (ac). the output signal can be modulated using a pwm signal.

this document describes the performance, technical data and the connection of the ssl21084 reference board. the ssl2108 series is an nxp semiconductors driver ic intended to provide a low cost, small form factor led driver. this board is intended to operate at 230 v (ac), using an output voltage of 30 v or more.
the board is optimized for a 230 v (ac, 50 hz) mains supply. in addition to the mains voltage optimization, the board is designed to work with multiple leds or an led module with a high forward voltage.
mains connection of this reference board is different from other general evaluation/demo boards. connect the mains to the screw connector j6.
