Part Number: TPS53915 Other Parts Discussed in Thread: TPS549B22 I found an article for a remote sensing application such that the ASIC itself is supplied with the full desired voltage (assuming a good ground with almost no voltage difference). I don…
Part Number: TPS53915 Hi, Could you tell me about TPS53915 /ALERT pin? 1.Is this pin open drain? 2.Is the pull-up voltage 1.8 V good enough? And Please tell me the recommended value of pull-up resistor. I believe that /ALERT pin conform to the PMBus standard…
Part Number: TPS53915 Hi,
Please find the attached schematic that generated using WEBENCH. The circuit is designed for 400KHz switching frequency with 12V input and the expected output is 1Volt at 8.5Amps .
Q1. Why is the MODE pin connected to VREG through…
Part Number: TPS53915 As pointed on the page 16 of datasheet the input voltage range (VIN) of TPS53915 can be from 1.5V to 18V, and the bias voltage (VDD) ragges from 4.5V to 25V. On the other hand from power supply recommendations on the page 40 follows…
Part Number: TPS53915 Hi, Could you tell me about TPS53915 internal Rvrm and Lvrm spec? Customers want that information for Altera's PLD tool. Could you give me a reference value for entering into the tool? I understand this value as information based…
Hi,
Please let me ask about tolerance of VOUT_ADJUSTMENT. Is following my understanding correct?
In case of +9% adj with VDACTOL1( typ ) : Vref = 600mV + 54mV = 654mV (+9%)
In case of +9% adj with VDACTOL1( min ) : Vref = 600mV + 54mV - 4.8mV = 649.2mV (+8.2…

I am not aware of a PMBus enabled termination LDO, but since the VTT and VTT_REF specification is 1/2 of VDDQ, a Tracking LDO without PMBus would generally be a valid, or even preferred solution to a programmable one. You can recommend the TPS51200…
Other Parts Discussed in Thread: TPS53915 , TINA-TI I downloaded the TPS53915 reference design for TINA-TI simulation and I get a convergence error at 1ms (52% completion). I have made no modifications to the circuit, so I expected no issues. Any idea why…
Other Parts Discussed in Thread: TPS53915 The spec for the TPS53915 describes I-VDD as 1850uA-max, but with "Power conversion enabled (no switching)". Not sure what this means and I need to know what the maximum VDD current is when there is switching.…
