Part Number: TPS61256C Other Parts Discussed in Thread: TPS61256 ic: TPS61256C
We are using this step-up dc-dc converter in the USB outputs of a device, with 3.3-4.2 V input and 5 V output. We have noticed that the BP bypass pin works contrary to what…
Hi Jian,
Please share the output ripple waveform.
The audible noise will not affect the regulator normal working. The 150uF tantalum capacitor is not needed. As the EVM is powered by the external power supply with long cables, the 150uF tantalum capacitor…
Part Number: TPS61256 I use tps61256 to supply power to the communication module. The maximum current of the communication module is 270ma, VIN = 3.9v, Vout = 5V. The schematic diagram is shown in Figure 1. The processor is mtk6763pcb, and en is connected…

The first set of Iq's is for operating and the second set of Iq's is for standby?
Operating:
Vin Iq (45uA) and Vout Iq 15uA)?
Standby:
Vin Iq (20uA…
Part Number: TPS61256 Hi team，
Our customer is now using TPS51256 and they want to know what's the difference between TPS51256 and TPS51256C. Do we have some comparison documents to share with customer?
Besides, do TPS61256 and TPS61256C have the…
Part Number: TPS61256
Hello,
I'd like to use the TPS61256 as a 5V regulator. It takes in 3.2-4.2VDC from a battery or 5DC when connected to USB. I want 5V on the output regardless of the voltage on the input. This regulator is going to drive a laser…
Part Number: TPS61256 Hi Team,
As datasheet mentioned, EN pin should not be left floating. But customer found, when EN is floating, the part is disabled. So just want to check on internal architecture of EN pin. Is it a high impedance on EN pin to GND…
