SLVAFQ9 January 2024 TPS92201
TPS92201 integrate analog dimming function converts digital PWM signal from SOC into FB pin as a voltage level. The TPS92201 is a high-efficiency, Adaptive off-time with peak current control scheme is adapted in the TPS92201. To get the smallest output ripple, the device operates at typically 1.5-MHz pulse width modulation (PWM) mode in full current range, At light load, the device automatically enters pulse frequency modulation (PFM) to maintain high efficiency over the entire load current range.
Compare with industry common design.
The following images are bench test results including efficiency and FB linearity and accuracy compared with TPS92201 and current design.
