Product details

Description

The A6210 is a buck regulator that uses valley current-mode control.

This control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching frequencies combined with high input voltages and low output LED span voltages.

Features

User-configurable on-time, achieving switching frequencies up to 2.0 MHz.
Brightness control through PWM of DIS pin.
Minimal external components required.
No output capacitor required.
Wide input voltage range: 9 to 46 V.
Low 0.18 V sense voltage for higher efficiency.
Output Current: up to 3.0 A.
Low standby current.
