Artikel-Nr.: HV9961NG-G

The HV9961 is an average current mode control LED driver IC operating in a constant off-time mode. Unlike HV9910B, this control IC does not produce a peak-to-average error, and therefore greatly improves accuracy, line and load regulation of the LED current without any need for loop compensation or high-side current sensing. The output LED current accuracy is ±3 %. The IC is equipped with a current limit comparator for hiccup-mode output short circuit protection. The HV9961 can be powered from an 8.0 ... 450 V supply. A PWM dimming input is provided that accepts an external control TTL compatible signal. The output current can be programmed by an internal 275 mV reference, or controlled externally through a 0 ... 1.5 V dimming input. HV9961 is pin-to-pin compatible with HV9910B and it can be used as a drop-in replacement for many applications to improve the LED current accuracy and regulation.

• Fast average current control
• Programmable constant off-time switching
• Linear dimming input
• PWM dimming input
• Output short circuit protection with skip mode
• Ambient operating temperature -40 ... +125° C
• Pin-compatible with the HV9910B

Technical Data:
• Topology: Buck
• Input Voltage: 8 ... 400 V
• Power: 1000 mW

Artikel-Nr.: HV9910CLG-G

The HV9910B is an open loop, current mode, control LED driver IC. The HV9910B can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 8.0 ... 450 V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. The HV9910B includes a PWM dimming input that can accept an external control signal with a duty ratio of 0 - 100% and a frequency of up to a few kilohertz. It also includes a 0 ... 250 mV linear dimming input which can be used for linear dimming of the LED current. The HV9910B is ideally suited for buck LED drivers. Since the HV9910B operates in open loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. PWM dimming response is limited only by the rate of rise and fall of the inductor current, enabling very fast rise and fall times. The HV9910B requires only three external components (apart from the power stage) to produce a controlled LED current making it an ideal solution for low cost LED drivers.

Artikel-Nr.: HV9120P-G

A unique input circuit allows the HV9120 to self-start directly from a high voltage input, and subsequently take the power to operate from one of the outputs of the converter it is controlling, allowing very efficient operation while maintaining input-to-output galvanic isolation limited in voltage only by the insulation system of the associated magnetic assembly. A ±2% internal bandgap reference, internal operational amplifier, very high speed comparator, and output buffer allow production of rugged, high performance, high efficiency power supplies of 50 W or more, which can still be over 80% efficient at outputs of 1.0 W or less. The wide dynamic range of the controller system allows designs with extremely wide line and load variations with much less difficulty and much higher efficiency than usual. The exceptionally wide input voltage range also allows better usage of energy stored in input dropout capacitors than with other PWM ICs. Remote on/off controls allow either latching or nonlatching remote shutdown. During shutdown, the power required is under 6.0 mW.

• 10 ... 450 V input voltage range
• <1.3 mA supply current
• >1.0 MHz clock
• >20:1 dynamic range @ 500 KHz
• 49% Maximum duty cycle version
• Low internal noise

Technical Data:
• Input Voltage: 10 ... 450 V
• Feedback: ±2%
