Switching frequency runs up to 1MHz, letting you shrink the magnetics and output capacitor, though the practical upper end depends on the MOSFET gate charge and the thermal budget in the 16-HTSSOP PowerPAD package. It includes synchronous rectification drive, so the external low-side FET replaces the freewheeling diode — efficiency gains are meaningful at higher output currents, especially in a 48V-to-12V telecom brick. ## Control features and duty cycle ceiling Built-in current limit, enable pin, frequency control, and soft start give you the basic supervisory and sequencing hooks without an external supervisor IC. Maximum duty cycle is 98%, which means the high-side FET stays on nearly the whole cycle at low dropout — useful when the input rail sags close to the output target. Single output, positive configuration, with clock sync support so multiple TPS40061 units can share a common switching frequency and avoid beat-frequency noise on the bus. ## Package, temperature grade, and compliance Supplied in tube packaging — the standard 16-HTSSOP footprint mates with any solder reflow profile for that package family.","metaTitle":"TPS40061PWP Buck Controller, 10-55V, 1MHz, 16-HTSSOP","metaDescription":"Active-production TPS40061PWP step-down buck controller from TI. 10V-55V input, up to 1MHz switching, 16-HTSSOP PowerPAD.
