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.
