3 Description
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.
