Part Number: TPS40090-Q1 Other Parts Discussed in Thread: TPS40090 , DRV10983-Q1 I use 5v PWM square wave connect to speed pin, but can`t control speed, speed is either very slow or fall speed.
i try to connect DC voltage , like 2.7v and 1.5V, the speed has…
Part Number: TPS40090-Q1 Hello,
Can you please confirm my understanding of datasheet terminology with regards to voltage levels on Enable pin:
"Enable threshold voltage"- voltage higher than the specified value will enable the device, voltages lower will…
Part Number: TPS40090-Q1 Other Parts Discussed in Thread: TPS40090 Hello Team,
I need help reviewing the compensation for a design using the TPS40090. Will send design files privately.
Part Number: TPS40090-Q1 Hi all,
I have two questions of TPS40090-Q1. Can you answer to the following questions?
Does this device have slope compensation to suppress the sub-harmonic oscillation?
Does Figure 3 in the datasheet typo as below?
Regards…
Part Number: TPS40090-Q1 Other Parts Discussed in Thread: TPS40090 , TPS40090EVM-001 , Hi,
I am currently working on some Pspice simulations with the TPS40090-Q1 Multiphase Buck Controller and I am having some problem getting the spice model to simulate…
Part Number: TPS40090-Q1 Hi Team,
I wanted to verify the startup operation of the TPS40090-Q1. According to the engineer i am working with he is seeing the following start up behavior, which in fact is not documented in the datasheet:
When EN pin goes…
Part Number: TPS40090-Q1 Does this chip has the following functions:
1. Short circuit protection;
2. Slope compensation;
3. I use external housekeeping 12V to power the IC. Can it be Used in High Voltage application (Vin = 100V; Vout = 24V; Pout = 3.5KW…
