The Texas Instruments TPS563200DDCR is a 4.5V to 17V input, 3A synchronous step-down (buck) converter in a 6-pin SOT-23 package. Using D-CAP2 control topology, it provides fast transient response with no external compensation components required. The integrated 68m\u03a9 high-side and 39m\u03a9 low-side MOSFETs achieve high efficiency, while Advanced Eco-mode maintains efficiency at light loads.<\/p>\n

It accepts input voltages from 4.5V to 17V and provides an adjustable output from 0.76V to 7V. Using D-CAP2 control topology, it achieves fast transient response with no external compensation components. The integrated 68m\u03a9 high-side and 39m\u03a9 low-side MOSFETs enable high efficiency without an external Schottky diode. Advanced Eco-mode maintains efficiency during light-load operation, while comprehensive protections (OCP, UVP, OVP, UVLO, TSD) ensure robust operation. The 650kHz fixed switching frequency and 1ms soft start simplify design.","working_principle":"The TPS563200 uses TI's D-CAP2 (Direct Connection to inductor with Adaptive Positioning, 2nd generation) control mode. This is a constant on-time, current-mode control architecture: (1) The feedback voltage (VFB) from the output resistor divider is compared to the 0.76V internal reference; (2) When VFB falls below the reference, the high-side MOSFET turns on for a calculated on-time proportional to VIN\/VOUT; (3) The low-side MOSFET turns on during the off-time, providing synchronous rectification; (4) An internal current-sense emulator injects an artificial ramp into the feedback signal for stable operation with low-ESR ceramic capacitors. In Advanced Eco-mode, at light loads the converter skips pulses to maintain efficiency. The 650kHz switching frequency is internally generated. Protection circuits include cycle-by-cycle current limiting, hiccup-mode UVP, and thermal shutdown at 150\u00b0C.","pin_description":"Pin Description(Output pin definitions in table format only; return pure content without derivation or extra elaboration)","application_scenarios":"Application Scenarios (Output pin definitions in table format only; return pure content without derivation or extra elaboration)","alternative_models":"TPS562200DDCR (2A version, 122m\u03a9\/72m\u03a9 FETs); TPS563209DDCR (fixed 5V output variant); TPS563252 (higher frequency, smaller package); RT8068AZQW (Richtek, 3A, 1MHz); SY8113 (Silergy, 3A, 1.4MHz)"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10570","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=10570"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10570\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=10570"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=10570"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=10570"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=10570"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
