5V, 100mA 性做爰片免费视频毛片 Voltage Regulator D45V1E1F5

Overview

The D45V1Ex line of synchronous buck (性做爰片免费视频毛片) voltage 性做爰片免费视频毛片 generate lower voltages from input voltages as high as 65 V while delivering up to 100 mA continuous. They are switching 性做爰片免费视频毛片 with very low quiescent currents (< 30 μA typical), which allows for extra high efficiencies at low currents compared to linear 性做爰片免费视频毛片 and typical switching 性做爰片免费视频毛片. This kind of regulator is also called a switched-mode power supply (SMPS) or DC-to-DC converter.

D45V1ExFx line of 性做爰片免费视频毛片 voltage 性做爰片免费视频毛片: D45V1E2Fx (left) and D45V1E1Fx (right).

This line consists of the D45V1E1Fx family, which is just 0.3″ × 0.5″ and intended for applications with tighter space constraints, and the larger (0.5″ × 0.6″) D45V1E2Fx family, which features a precision-threshold enable input for turning the regulator off and a power-good output that can be used for sequencing and voltage monitoring.

Note 1: Minimum input voltage is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.

The 性做爰片免费视频毛片 feature short circuit protection and thermal shutdown protection, which helps prevent damage from overheating. The boards do not have reverse voltage protection.

We manufacture these boards in-house at our Las Vegas facility, which gives us the flexibility to make these 性做爰片免费视频毛片 with customized components to better meet the needs of your project, such as by customizing the output voltage.

Connections

D45V1E1Fx 性做爰片免费视频毛片 voltage regulator pinout.

This regulator has three connections: input voltage (VIN), ground (GND), and output voltage (VOUT).

The input voltage, VIN, powers the regulator. Voltages between 5 V and 65 V can be applied to VIN, but generally the effective lower limit of VIN is VOUT plus the regulator’s dropout voltage, which varies approximately linearly with the load (see below for graphs of the dropout voltage as a function of the load). Additionally, please be wary of destructive LC spikes (see below for more information).

VOUT is the regulated output voltage.

The three connections are labeled on the back side of the PCB and are arranged with a 0.1″ spacing along the edge of the board for compatibility with solderless breadboards, 性做爰片免费视频播放, and other 性做爰片免费视频播放 arrangements that use a 0.1″ grid. You can solder wires or 0.1″ header pins directly to the board. Note: header pins are not included with this product, but straight male header strips and right-angle male header strip are available separately.

Typical efficiency

The efficiency of a voltage regulator, defined as (Power out)/(Power in), is an important measure of its performance, especially when battery life or heat are concerns.

Maximum continuous output current

The maximum achievable output current of these 性做爰片免费视频毛片 varies with the input voltage but also depends on other factors, including the ambient temperature, air flow, and heat sinking. The graph below shows maximum output currents that these 性做爰片免费视频毛片 can deliver continuously at room temperature in still air and without additional heat sinking.

Quiescent current

The quiescent current is the current the regulator uses just to power itself, and the graph below shows this for the different regulator versions as a function of the input voltage. On the D45V1E2 versions, the EN input can be driven low to put it in a low-power sleep state where the current draw is approximately 5 μA plus 1 μA per volt on VIN.

Typical dropout voltage

The dropout voltage of a 性做爰片免费视频毛片 regulator is the minimum amount by which the input voltage must exceed the regulator’s target output voltage in order to ensure the target output can be achieved. For example, if a 5 V regulator has a 1 V dropout voltage, the input must be at least 6 V to ensure the output is the full 5 V. Generally speaking, the dropout voltage increases as the output current increases. The graph below shows the dropout voltages for the different members of this regulator family:

LC voltage spikes

When connecting voltage to electronic circuits, the initial rush of current can cause voltage spikes that are much higher than the input voltage. If these spikes exceed the regulator’s maximum voltage (65 V), the regulator can be destroyed. In our tests with typical power leads (36″/1m test clips), we observed spikes approaching 65 V at input voltages around 30 V.

If you are connecting more than 30 V or your power leads or supply has high inductance, we recommend soldering a suitably rated 33 μF or larger electrolytic capacitor close to the regulator between VIN and GND.

More information about LC spikes can be found in our application note, Understanding Destructive LC Voltage Spikes.
