Part Number: UCC20225-Q1 Other Parts Discussed in Thread: UCC20225 , TPS2838 Tool/software: Hi,
I want to use UCC20225 gate driver for the synchronous buck design. The design is 10:1 ratio. If the PWM duty cycle as input to the UCC20225, is 10%, would…
Hi Ajmal,
Yes, you could use TPS2838 with UCC28C42. However, the high output resistance the TPS2838 has will make the switching loss high.
If you are targeting to have lower ripple current, you also will have to operate in continuous current conduction…
Part Number: UCC28C42 Other Parts Discussed in Thread: TPS2838 Hi,
I am looking for a converter design with the input of 50VDC-300VDC and output is 14VDC/6A. No isolation requirement.
Can I use UCC28C42 along with synchronous driver IC TPS2838?. UCC28C42…
Other Parts Discussed in Thread: TPS2838 , LM5106 , LM5109B-Q1 , TPS2836 Hello all,
I am just new with these type of drivers: TPS2838/38/48/49. They are called 'Synchronous-Buck MOSFET Drivers'. My question is, can they be used only for driving buck…
Hi Randy,
UCC27282 is our latest half-bridge driver, it is rated for -40C to 125C, includes a 5V UVLO and offers better drive current and switching characteristics.
The devices below are a good starting point.

TPS2838…
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…
