TLD5099EP数据手册开发板套件编程器的评估板-LED驱动器规格书PDF

描述 Description

It also includes an integrated pulse width modulator to easily implement a dimming function with reduced color shifting and a spread spectrum modulator to improve the EMI performance. It is designed to support fixed current and fixed voltage configurations in multiple topologies such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. The TLD5099EP drives a low side n-channel power MOSFET from an internal 5 V linear regulator.

特性 Features

• Fixed current or fixed voltage configuration in Boost, Buck, Buck-Boost, SEPIC and Flyback topology
• Drives low-side external n-channel switching MOSFET from internal 5 V voltage regulator
• Flexible switching frequency range from 100 kHz to 500 kHz with spread spectrum modulator
• Synchronization with external clock source
• Wide input voltage range from 4.5 V to 45 V
• Enable & PWM functions with very low shutdown current: IQ_OFF < 15 µA at 105°C
• Analog dimming and PWM dimming feature (embedded or external) to adjust average LED current
• PWMO gate driver for PWM dimming and output disconnection

应用 Application

• Automotive exterior and interior lighting
• General illumination
• General purpose current/voltage controlled DC-DC driver
