HT7L2102规格书详情
Description
The HT7L2102 is an advanced, highly integrated LED Lighting driver using an AC-DC isolation topology. The device provides many protection functions and uses ultra low power circuit design, and is optimized to restrict EMI. By integrating a Non-Audible Noise Green Mode Control Structure, users can implement a single circuit for different LED load levels for various series/parallel configurations but still maintain high efficiency for different load conditions. This device also integrates various protection functions for LED Lighting requirements such as Cycle-by-Cycle Current Limiting, Short-Circuit Protection (SCP), Over-Voltage Protection (OVP), Over-Temperature Protection (OTP) for external thermistor sensing, and a Soft-Start function to reduce inrush currents during LED power system initialization for the prevention of device burn-out.
The HT7L2102 provides a 1~99 PWM Dimming Range with duty-cycle scale precision lower than 1.
Feature
• Frequency Jitter for EMI Restriction
• Integrated Soft-Start Function
• Very Low Operating Current and Start-up Current (<20mA) for satisfying Energy-Star 2.0 No-Load Mode (Stand-by) Power standard
• ±5 Trimmed Oscillator for Precise Frequency
• Non-Audible-Noise Green Mode Control to maintain efficiency for both Light and Heavy Loads
• LEB (Leading-Edge Blanking) on CS Pin
• Internal Slope Compensation
• Cycle-by-Cycle Current Limiting
• Short-Circuit-Protection(SCP) for Short-Circuit and Over-Load Condition
• Over-Voltage-Protection(OVP) on VCC Pin
• Over-Temperature-Protection(OTP) on TS pin for External Thermistor Sensing
• 1~99 PWM Dimming Range
• 8-pin SOP package
Applications
• Isolation AC-DC LED Lighting
• AC-DC Switching Power Supply/Adapter
