Overview
HM5669 General Description HM5669 develops a step-up DC/DC converter that delivers an accurate constant current for driving LEDs.
Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor.
The LED current is programmable through the external resistor.
The device also supports PWM dimming for accurate LED current control.
HM5669 is ideal for driving up to eight white LEDs in series or up to 30V.
