There is no limitation on the input capacitor size, but the bigger input cap, the higher input inrush current, you need to consider the impact of inrush current and limit if necessary.
Part Number: LMR33630LMR33630 is used to generate 3.3V from 3.8V with 50mA load. A negative inductor current is observed during switching.
1. Can this negative current impact stability of the module?
2. What is the cause for negative current observed…
Part Number: LMR33630 Hi Team, seeking for some inputs.
Upon power cycling, I sometimes see the output is only 2 - 2.4 Volts, the problem occurs maybe 2 out 35 power cycles. The circuit is biased for a 5V at a Fsw of 400kHz.
Part Number: LMR33630 Hello guys,
I have tried to simulate on PSpice, the proposal schematic from Webench tool - 12V to 5V/3A, using LMR33630B, but for some reasons that i dont know the output dont match with the Webench tool, the capacitors are very…
Part Number: LMR33630 Hi Expert,
I see below description in "Working With Inverting Buck-Boost Converters". IBB has much lower efficiency than buck. Why do they have so much loss difference? What's the major power loss increase? Thanks. …
Part Number: LMR33630 Dear TI,
I am designing an electronic access control system which must provide power to peripherals at 12VDC and, in some cases, 24VDC, with total output current from 0 to 3A. The system is powered from a 32V AC/DC PSU with battery…
Part Number: LMR33630-Q1 Other Parts Discussed in Thread: LMR33630 Hello Team,
do we have specification for the switching node regarding rise and fall-time? Also, is there a specification of the low side diode available such as forward voltage?
