ABSOLUTE MAXIMUM RATINGS

QFN-19 (3mmx4mm)

V_IN- V_PGND/AGND..............................-0.3V to +50V

V_IN- V_INGND....................................-0.3V to +50V

V_INGND- V_PGND/AGND.........................-0.3V to +50V

V_FAULT- V_INGND...............................-0.3V to +50V

V_EN/DIM- V_INGND..............................-0.3V to +5.5V

V_SW- V_PGND/AGND-0.3V to V_IN- V_PGND/AGND+ 0.3V

All other pins - V_PGND/AGND.............-0.3V to +5.5V

Continuous power dissipation (T_A= 25°C) ^{(2) (4)}

QFN-19 (3mmx4mm)................................. 3.9W

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

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

Storage temperature................ -65°C to +150°C

JESD51-7 ⁽³⁾...........................48...... 11... °C/W

EVQ7200-L-00A ⁽⁴⁾.................32....... 6.... °C/W

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 can cause excessive die temperature, and the

regulator may go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

3) Measured on JESD51-7, 4-layer PCB. The value of θ_JAgiven

in this table is only valid for comparison with other packages

and cannot be used for design purposes. These values were

calculated in accordance with JESD51-7 and simulated on a

specified JEDEC board. They do not represent the

performance obtained in an actual application.

ESD Ratings

Human body model (HBM) ........................±2kV

Charged device model (CDM) ................ ±750V

4) Measured on MPS standard EVB of MP7200, 2oz, 4-layer

PCB.

LED current (I_LED) in buck mode ...........Up to 3A

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