PRODUCTION DATA
The TPSM86325x is a 3A, integrated, FET, synchronous buck module that operates from 3V to 17V input voltage and TPSM863252 output voltage range is 0.6V to 10V. TPSM863257 output voltage range is 0.6V to 5.5V. TPSM863253 is fixed 3.3V output voltage version. The device employs a D-CAP3 control mode that provides fast transient response with no external compensation components and an accurate feedback voltage. The proprietary D-CAP3 control mode enables low external component count, ease of design, and optimization of the power design for cost, size, and efficiency. The topology provides a seamless transition between CCM operating mode at higher load condition and DCM operation mode at lighter load condition.
The Eco-mode version allows the TPSM863252 to maintain high efficiency at light load. The FCCM version allows the TPSM863253 and TPSM863257 to maintain a fixed switching frequency and lower voltage output ripple. The TPSM86325x is able to adapt to both low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors.
