Part Number: TPS61021A Other Parts Discussed in Thread: TIDA-01387 , , TPS61033 App Note TIDA-01387 describes "how to power GPRS modules in smart meters using LISOCL2 batteries. GPRS modules require peak current of up to 2 A"
This app note re…
Part Number: TIDA-01387 Other Parts Discussed in Thread: TPS61021A Hi,
Noticed that there is no diode (to prevent reverse current) and current limiting resistor between the Li-SOCL2 battery and the supercapacitor in TIDA-01387 schematic. But in the design…
Part Number: TIDA-01387 Other Parts Discussed in Thread: TPS61021A Can I use this zener diode: MMSZ4689T1 instead of the original one - 1SMB5918BT3G used in the design?
Also Ive created a gsm supply using reference design. Could you please review the layout…
Part Number: TIDA-01387 Hey
The inductor with part no. XFL4015-471MEC used in this reference design
is not available with my distributor and is also very costly. Could you please
help me select an alternative part from one of the inductors listed here…
Part Number: TIDA-01387 Hello, Given the product specs of 2A continuous peak current, 3.3V Vmin and 4.6V Vmax, How do we end up requiring 5.4V, 20F supercapacitor? What is the duration of the continuous peak current? I do understand that supercapacitor…

Hey
The KAMAP capacitors listed in the BOM with part description: CAP, AL, 20 F, 5.4 V, +/- 20% do not seem to exist.
Could you please suggest alternative capacitor part no.s.
Also will it be OK if instead of using these super…
Hello helen,
No, i am recently working on FRAM device because i switched MCU ATMEL to TI so i was quite busy learning some Low power technique in MSP430 devices. And Can you suggest any link TIDA-01387 readymade EVM.
1. about the TPS61021A, it can't support continued 4V 2A. but in your application, the 2A should be pulsed current, which can support through aluminum capacitor. as in this reference design " www.ti.com/.../TIDA-01387"
2. The TPS61030 layout…
