TPS61088 Adjustable Boost Step Up Board Module Switching Power Supply Module PWM 10A Current 1MHz Switching Frequency

Module Introduction:

The module adopts TI TPS61088 power chip solution, which has stable performance, small ripple, 10A switching current capability, and switching frequency of about 1MHZ. The module provides two working modes: PWM and PFM.

Users can adjust by themselves (default PWM mode shipment), on-board high-quality tantalum capacitors and flat copper wire inductors, using high-quality components to further improve the performance and stability of the module.

When the module outputs high power, it still has the stability that most other booster modules can't match. When users use multi-cell lithium batteries in parallel to boost the application to 5V voltage and 4A/5A output high current, it is a A good choice, the same voltage boost to 9V/12V is not a problem, the output power can reach up to 30W, 9V, 12V voltage output, when outputting a large current, the user only needs to do a good job of heat dissipation to obtain a good belt. carrier output ripple. Unless otherwise specified, the following parameters are tested in PWM mode.
