Part Number: TLV61225 I use in my product that I develop TLV61225 to generate 3.3 volts from lithium battery type 123 (3 volts). Most of the time the current is about 100microAmper, when in use for 10 seconds the current drawn about 10 to 100 mA.

Hi,
Any update please regarding my circuit with tlv61225?
Is there anything to change to improve my design based on coin cell battery cr1632 to provide at output 3-3.V with 100-150mA?
Many thanks
Regards,
Mourad
Part Number: TLV61225 Hello E2E,
I understand that this device operate by controlled ripple current.
Inductor current ripple is 200mA and switch_current_limit(min) is 160mA on datasheet.
Can this device startup?
Regards, ACGUY

Part Number: TLV61225 Hi Team,
Are you able to provide the expected voltage drop of the diode when the device is in shutdown mode? I was not able to find this in the datasheet, but am not sure if I missed it. this would be for an application boost…

Part Number: TLV61225 Hi team,
My customer has a question regarding TLV61225:
"On our working prototype PCB, if EN=VIN=3.0V, VOUT=3.3V. If EN=0V and VIN=3.0V, VOUT stays at 3.3V. To save power, we want to shut this chip down to keep current under…
Other Parts Discussed in Thread: TLV61225 Hi!
I was wondering if the TLV61225 can be operated in shutdown mode with VIN 0V or VIN > 0V while VOUT is supplied from another source and > 0V. The datasheet mentions this:
During shutdown, the converter…
could you help to measure the VIN, SW and VOUT waveform of the "short circuit" behavior you observed?
as the input power is limited, coil cell or 100mA power supply, the boost converter start up behavior and the maximum load power are matter.
avoid…
The load current is far, far lower than 30 µA. It's likely on the order of 10 µA or less. The load is an ATTiny45 with a 32 kHz system clock in idle mode.
But for 35 ms about once per second the load current will jump up to 5 mA or so. But most of the…
