Texas Instruments TLV62565DBVR

The TLV62565/6 devices are synchronous step-down converters optimized for small solution size and high efficiency. The devices integrate switches capable of delivering an output current up to 1.5 A.

The devices are based on an adaptive on time with valley current mode control scheme. Typical operating frequency is 1.5 MHz at medium to heavy loads. The devices are optimized to achieve very low output voltage ripple even with small external components and feature an excellent load transient response.

During light load, the TLV62565/6 automatically enter into Power Save Mode at the lowest quiescent current (50 µA typ) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is reduced to less than 1 µA.

The TLV62565/6 provide an adjustable output voltage via an external resistor divider. The output voltage start-up ramp is controlled by an internal soft start, typically 250 µs. Power sequencing is possible by configuring the Enable (TLV62565) and Power Good (TLV62566) pins. Other features like over current protection and over temperature protection are built-in. The TLV62565/6 devices are available in a SOT-23 5-pin package.

 

德克萨斯仪器tlv62565dbvrthe tlv62565 / 6设备的同步降压转换器解决方案的小尺寸和高效率的优化。该设备集成了能够提供输出电流达1.5 A的开关。

该器件是基于谷电流模式控制方案的自适应时间。典型的工作频率为1.5兆赫在中重负荷。该器件进行了优化,以达到非常低的输出电压纹波,即使是小的外部元件,具有出色的负载瞬态响应。

在轻负载的tlv62565 / 6自动进入功率最低的静态电流省电模式(50µ一典型)在整个负载电流范围内保持高效率。在关断,电流消耗降低到小于1µA.

的tlv62565 / 6提供了一个可调输出电压通过外部电阻分压器。输出电压启动斜坡是由一个内部软启动控制,通过配置使通常250µS.电源排序是可能的(tlv62565)和Power Good(tlv62566)引脚。其他功能,如过流保护和过热保护是内置的。的tlv62565 / 6设备在SOT-23 5引脚封装可。
