評価ボード詳細をご覧ください。
製品説明
The EV44014-S+HR1001-S-01A is a general purpose evaluation board of MP44014, HR1001B, MP6922 and MP174 for 240W LED driver & Adapters application.
The MP44014 is a boundary conduction mode PFC controller which can provide simple and high performance active power factor correction using minimum external components.
The HR1001B is an enhanced LLC controller which provides new features of adaptive dead time adjustment (ADTA) and capacitive mode protection (CMP).
The MP6922 is a dual fast turn-off intelligent rectifier to drive two N-CH power MOSFETs in LLC resonant converters for synchronous rectification.
The MP174 is a primary-side regulator that provides accurate constant voltage (CV) regulation without opto-coupler.
Typically, the EV44014-S+HR1001-S-01A is designed for LED driver &adapters with a 12 V, 20 A constant voltage output and 240W rated power, from 90 VAC to 265 VAC, 50 Hz/60 Hz.
The EV44014-S+HR1001-S-01A has excellent efficiency and high power factor. Besides, the EV44014-S+HR1001-S-01A has output fault protections, such as over load protection, short circuit protection, over voltage protection and anti-capacitive mode protection. It also can meet the Class C standard of IEC61000-3-2 and EN55022 standard.

パラメータ
Offline PFC controller, boundary conduction mode
The MP44014 is a boundary conduction mode PFC controller that provides simple, high-performance, active power factor correction using minimal external components.
The output voltage is regulated accurately by a high-performance voltage mode amplifier with an accurate internal voltage reference.
The precise, adjustable output over-voltage protection greatly enhances system reliability.
The on-chip R/C filter on the current sense pin can potentially eliminate the external R/C filter.
The extremely low start-up current, quiescent current, and disable function reduces power consumption, resulting in excellent efficiency performance.
The MP44014 is available in a SOIC-8 package.
