The TPS92201 is a high-efficiency 1.5A synchronous buck-type LED driver with 2.5V to 5.5V input range. By integrating the high-side and low-side MOSFET, high efficiency and compact solution size can be achieved. The ultra-low 1µA shutdown current helps saving power in battery-powered applications.
Adaptive off-time with peak current control scheme is adapted in the TPS92201. To get the smallest output ripple, the device operates at typically 1.5MHz pulse width modulation (PWM) mode in full current range.
Adaptive off-time with peak current control scheme is adapted in the TPS92201A. At medium to heavy load, the device operates in pulse width modulation (PWM) mode with 1.5MHz switching frequency. At light load, the device automatically enters pulse frequency modulation (PFM) to maintain high efficiency over the entire load current range.
The integrated switches have the capability to deliever up to 1.5A constant current. Analog dimming is achieved by adjusting the duty cycle of the PWM input with 1% to 100% range. 20kHz to 200kHz input PWM frequency can be supported to avoid audible noise.
For safety and protection, the TPS92201 device implement full protections, including LED open, LED short, FB resistor open, FB resistor short and thermal shutdown.
