Output Short-Circuit Protection Reference Design for the TPS61088 Boost Converter
Description
This reference design delivers an output short-circuit protection solution for the TPS61088 boost converter. This feature is realized by an over current protection (OCP) circuit. When the output is shorted to ground or the load current is higher than a certain value: the OCP circuit will disconnect the TPS61088 from the load. This solution only requires an additional low-cost comparator: a sense resistor: and a small sized N-MOSFET. With this small amount of additional circuitry: the TPS61088 is protected from being damaged in the output short circuit and over load conditions.
Features
- 2.7V to 4.2V input voltage range5V/3A: 9V/2A and 12V/1.5A output capabilityOutput short circuit and over load protectionTrue disconnection between input and output during shut downIdeal for power bank: blue-tooth speaker application: etc.
