The Future of Analog IC Technology
DESCRIPTION
The MP2305S is a monolithic synchronous
buck regulator. The device integrates a 175m
high-side MOSFET and a 115mlow-side
MOSFET that provide 2A continuous load
current over a wide operating input voltage of
4.75V to 23V. Current mode control provides
fast transient response and cycle-by-cycle
current limit.
An adjustable soft-start prevents inrush current
at turn-on. Shutdown mode drops the supply
current to 1μA.
This device, available in an 8-pin SOIC
package, provides a very compact system
solution with minimal reliance on external
components.

Operating Junct. Temp. (TJ) ..........-40°C to +125°C
Thermal Resistance (4) θJA θJC
SOIC8..................................... 90 ...... 45... °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 TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. 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.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4-layer PCB.
