This datasheet also covers the SY7201 variant, as both devices belong to the same 30v high current boost led driver family and are provided as variant models within a single manufacturer datasheet.
General Description
SY7201 and SY7201A are DC/DC step-up converters that deliver an accurate constant current for driving LEDs.
Operation at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor.
Key Features
Input voltage range: 2.8 to 30V.
Switch current limit 2A.
Drives LED strings up to 30V.
1MHz fixed frequency minimizes the external
components.
Dimming frequency for EN/PWM pin:
ο SY7201: 20kHz~1MHz ο SY7201A: 100Hz~10kHz.

SY7201A are DC/DC step-up converters that deliver an accurate constant current for driving LEDs. Operation at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the external resistor. The SY7201 and SY7201A are ideal for driving up to eight white LEDs in series or up to 30V.
