DC-DC Non-Sync Step Up Convert from Qorvo

40 V White LED Step-Up DC/DC Converter / Bias Supply

Status: Discontinued | Datasheet: Request Data Sheet | RoHS Compliance: Rohs Compliant

Overview

Qorvo’s ACT6358 is a step-up DC/DC converter that is used to drive white LEDs with an externally programmable constant current. The device features integrated 40 V power MOSFETs that are capable of driving up to ten white LEDs in series, providing inherent current matching for uniform brightness. WLED brightness adjustment is easily achieved via a dual-function pin, which accepts either a PWM or an analog dimming control signal.

The product features a variety of protection circuits, including integrated over-voltage protection (OVP), programmable soft-start, cycle-by-cycle current limiting and thermal shutdown protection circuitry. The product has a 1 A current limit.

ACT6358 is available in a small 3mm x 3mm 8-pin TDFN33-8 package.
