Datasheet

详情

The MP3362 is a fixed-frequency converter ideal for low-current and high-current boost applications. The low 0.2V feedback voltage offers higher efficiency in white LED driver applications.

The MP3362 regulates the output voltage up to 36V with efficiency as high as 95%. Current mode regulation and external compensation components allow the MP3362 control loop to be optimized across a wide variety of input voltages.

The MP3362 supports analog dimming and PWM dimming on the same pin. A <2kHz input dimming frequency initiates PWM dimming, while an >5kHz input initiates analog dimming.

Soft start, cycle-by-cycle current limiting, and input under-voltage lockout prevent overstressing or damaging sensitive external circuitry during start-up or potential overload current conditions.

The MP3362 is available in a TSOT23-8 package.

Advantages Include:

Wide input voltage range and high peak current
Internal power switch and high efficiency
Analog dimming and PWM dimming
Good circuit protection and AECQ-100 available

EVQ3362-J-00A 单串、3V V_{IN_MIN}、36V V_OUT、升压（Boost） LED 驱动器评估板，符合 AEC-Q100 认证

EVQ3362-J-00A 是一款用于演示 MPQ3362 产品性能的评估板。MPQ3362 是一款升压 LED 驱动器，非常适合低-高电流升压应用。MPQ3362 的 0.2V 低反馈电压（VFB）可在白光 LED（WLED）驱动器应用中提供更高的效率。它能在高达 36V 的电压下调节输出电压（VOUT），效率高达 95%。在 3V 至 36V 宽输入电压（VIN）范围内，电流模式调节和外部补偿可优化 MPQ3362 的控制环路。

MPQ3362 在 EN/DIM 引脚上支持模拟调光和脉宽调制（PWM）调光。<2kHz 输入调光频率可启动 PWM 调光，而 >5kHz 输入调光频率可启动模拟调光。
软启动（SS）、逐周期限流保护和 VIN欠压锁定（UVLO）保护可防止器件承受过大应力或损坏。这样可在启动和欠载/过载条件下保护敏感的外部电路。

MPQ3362 采用 TSOT23-8 封装。
