LM25005开关稳压器具有所有必要的功能来实现一个高效率，高电压降压稳压器使用最少的外部元件。 这种易于使用的稳压器包括一个42V，160mΩ，N沟道MOSFET，2.5安培的电流输出能力。 The regulator is controlled using an analog current ramp according to the current mode. 电流模式控制提供固有的线电压前馈，逐周期电流限制和简化环路补偿。 The sensitivity of the pulse-width modulation circuit using the analog control ramp to reduce noise allows for very small duty cycles necessary for reliable control in high input voltage applications. The operating frequency is programmable from 50kHz to 500kHz. 振荡器同步引脚允许多个LM25005稳压器自动同步操作或同步至一个外部时钟。 Other protection features include current limiting, thermal shutdown, and remote shutdown capability. Enhanced TSSOP-20 packages are available in power equipment with an exposed die bonding pad to aid in heat dissipation.
