MPQ3369 – 6-CHANNEL, BOOST WLED DRIVER W/ HIGH DIM RATIO AND I²C

Thermal Resistance ⁽⁴⁾

QFN-24 (4mmx4mm)….…....…42…….9....°C/W

θ_JA

θ_JC

(1)

ABSOLUTE MAXIMUM RATINGS

V_IN.................................................-0.3V to +42V

V_SW, V_LED1to V_LED6.........................-0.5V to +50V

V_SW.......................................... -1.0V for <100ns

V_SD................................................V_IN- 6V to V_IN

All other pins...................................-0.3V to +6V

Junction temperature................................150°C

Lead temperature .....................................260°C

Continuous power dissipation (T_A= 25°C) ⁽²⁾

QFN-24 (4mmx4mm)............................... 2.97W

Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature, T_J(MAX), the junction-to-

ambient thermal resistance, θ_JA, and the ambient temperature,

T_A. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by P_D(MAX) = (T_J

(MAX) - T_A) / θ_JA. Exceeding the maximum allowable power

dissipation will cause excessive die temperature, and the

regulator will go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

ESD Rating

3) The device is not guaranteed to function outside of its operating

conditions.

4) Measured on JESD51-7, 4-layer PCB.

Human body model (HBM)

LED1-6 ESD ................................................ 8kV

All other pins................................................ 2kV

Charged device model (CDM) .................... 2kV

Recommended Operating Conditions ⁽³⁾

Supply voltage (V_IN) .........................3.5V to 36V

Operating junction temp (T_J).... -40°C to +125°C
