A first transconductance amplifier adjusts an output current at the output pin and operates in a constant voltage mode. The first transconductance amplifier includes a first positive input to receive a first voltage reference and a first negative input coupled to a tap point of a voltage divider coupled between a voltage bus and a ground of the buck-boost converter. A second transconductance amplifier also adjusts the output current at the output pin and operates in a constant current mode. The second transconductance amplifier includes a second positive input to receive a second voltage reference and a second negative input coupled to a current sense amplifier, the current sense amplifier being coupled to a sense resistor positioned inline along the voltage bus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transconductance amplifier for buck-boost converter","description":"An error amplifier includes an output pin coupled to a pulse width modulation (PWM) comparator of a buck-boost converter.
