MP1477 – SYNCHRONOUS, STEP-DOWN CONVERTER WITH INTERNAL MOSFETS

ABSOLUTE MAXIMUM RATINGS ⁽¹⁾

VIN ................................................ -0.3V to 18V

V_SW............................-0.6V (-6.5V for <10ns) to

VIN + 0.3V (19V for <10ns)

Thermal Resistance

SOT563

θ_JA

θ_JC

(5)

EV1477-TF-00A ................ 55.......21 ... °C/W

(6)

JESD51-7 ........................ 130......60 ... °C/W

V_BST.....................................................V_SW+ 5V

(2)

NOTES:

V_EN..............................................-0.3V to 5V

1) Exceeding these ratings may damage the device.

2) For details on EN’s ABS max rating, please refer to the EN

Control section on page 11.

All other pins.................................... -0.3V to 5V

(3)(5)

Continuous power dissipation (T_A= +25°C)

3) 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 produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

..................................................................2.2W

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

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

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

Recommended Operating Conditions ⁽⁴⁾

Supply voltage (VIN)....................... 4.2V to 17V

Output voltage (V_OUT).........0.8V to V_INх D_MAXor

10V max

4) The device is not guaranteed to function outside of its

operating conditions.

5) Measured on EV1477-TF-00A, 2-layer PCB.

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

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