Part Number: REG710-3 Hello ,
About input current at input voltage near setting output voltage
Regarding to input current on REG710, my customer is asking a question.
(Question)
According to figure 8 in datasheet,
It seems that when input…
Part Number: REG71050 Other Parts Discussed in Thread: REG710-5 , REG710-3 , TPS61299 Hello,
I'd like to use the REG71050 for boosting an input that ranges between 1.8 V and 3 V. The dataheet table for input operating voltages, table 7.3, indicates…
Part Number: REG710-33 Other Parts Discussed in Thread: REG710-3 I designed my circuit with REG710-3.3V (Fxied output voltage) model.
[Issue statement]
Output voltage is 1.69V when EN pin is pulled low.
** Note: When my mcu give HIGH on EN pin…
Other Parts Discussed in Thread: REG710-3 I'm using the reg710-3.3 (SOT23-6 package) in a battery powered application and see excessive quiescent current when ENA is pulled low. Should be < 1uA according to the spec, but I'm seeing up to 900uA through…
The output voltage accuracy (which depends on the reference voltage accuracy, as shown in section 8.2) is pretty much independent from the input voltage, so the resulting graph would contain just several horizontal lines (as in the TLV767 example). Whoever…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
