HVLED007 Overview
Key Specifications
Package: SOP
Length: 4.9 mm
Width: 3.9 mm
Max Operating Temp: 125 °C
Description
The HVLED007 is a current-mode PFC controller specific for isolated high power factor, flyback Datasheet - Production data converters operated in transition mode (aka quasi-resonant operation). Targeting both indoor and outdoor solid-state lighting applications, it provides extended temperature range operation down to -40 °C with guaranteed electrical specification.
Key Features
- Transition-mode (quasi-resonant) control of flyback PFC pre-regulators
- Proprietary input current shaper for minimum THD of line current
- Control input for isolated feedback and optocoupler driving
- Output overvoltage protection
- Overload and short-circuit protection
- Low (≤ 60 μA) start-up current and low (≤ 4 ma) quiescent current
- Digital leading-edge blanking on current sense
- 600/+800 mA totem pole gate driver with UVLO pull-down and voltage clamp
