MP2152D – 2.5V TO 5.5V, 2A, LOW I_Q, SYNC, STEP-DOWN CONVERTER

PIN FUNCTIONS

Name

(SOT563

Pin #

Description

and

UTQFN-6)

GND

Power ground.

Output switching node. The SW pin is the drain of the internal, P-Channel high-side

MOSFET (HS-FET). Connect SW to the inductor to complete the converter.

Supply voltage. The MP2152D operates from a 2.5V to 5.5V unregulated input voltage

(V_IN). Use a decoupling capacitor to prevent large voltage spikes at the input.

On/off control.

Feedback. To set the output voltage (V_OUT), connect an external resistor divider tapped to

the FB pin between the output and GND.

VIN

Output sense. The OUT pin is the voltage power rail and input sense for V_OUT. Use an

output capacitor (C2) to reduce the output voltage ripple (∆V_OUT).

ABSOLUTE MAXIMUM RATINGS

Supply voltage (V_IN) .................................... 6.5V

V_SW................................-0.3V (-5V for <10ns) to

+6.5V (10V for <10ns)

All other pins................................-0.3V to +6.5V

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

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

JESD51-7 ^{(6) (7) (8)}…………….130…....60…°C/W

UTQFN-6 (1.2mmx1.6mm)

EVL2152D-QFU-00A ⁽⁵⁾………65…….30…°C/W

JESD51-7 ^{(6) (7) (8)}……………..173......127…°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 produce an excessive die temperature, which

may cause the regulator to go into thermal shutdown. Internal

thermal shutdown circuitry protects the device from permanent

damage.

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

conditions.

4) Measured on EVL2152D-TF-00A, 2-layer PCB.

5) Measured on EVL2152D-QFU-00A, 2-layer PCB.

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

7) The value of θ_JAgiven in this table is only valid for comparison

with other packages and cannot be used for design purposes.

8) These values are calculated in accordance with JESD51-7,

and simulated on a specified JEDEC board. They do not

represent the performance obtained in an actual application.

Supply voltage (V_IN) ........................2.5V to 5.5V
