The Future of Analog IC Technology
DESCRIPTION
The MP2315S is a high-efficiency, synchronous,
rectified, step-down, switch mode converter
with built-in, internal power MOSFETs. It is a
next generation of the MP2315. It offers a very
compact solution to achieve 3A continuous
output current over a wide input supply range
with excellent load and line regulation.
The MP2315S uses synchronous mode
operation for higher efficiency over the output
current-load range. Current mode operation
provides fast transient response and eases loop
stabilization.
Full protection features include over-current
protection (OCP), over-voltage protection
(OVP), and thermal shutdown.
The MP2315S requires a minimal number of
readily available, standard, external
components and is available in a compact
TSOT23-8 package.

NOTES:
1) Exceeding these ratings may damage the device.
2) For details on EN’s ABS MAX rating, please refer to the
Enable Control section on page 9.
3) 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 produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
4) The device is not guaranteed to function outside of its
operating conditions.
5) Measured on JESD51-7, 4-layer PCB.
