MP2361
2A, 23V, 1.4MHz
Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP2361 is a monolithic step-down switch
mode converter with a built-in internal power
MOSFET. It achieves 2A continuous output
current over a wide input supply range with
excellent load and line regulation.
Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protections include cycle-by-cycle
current limiting and thermal shutdown. In
shutdown mode the regulator draws 20μA of
supply
current.
Programmable
soft-start
minimizes the inrush supply current and the
output overshoot at initial startup.
The MP2361 requires a minimum number of
readily available standard external components.

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

, and the ambient temperature
T

. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P

. 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.

No Connect.
Bootstrap (C5). This capacitor is needed to drive the power switch’s gate above
the supply voltage. It is connected between SW and BS pins to form a floating
supply across the power switch driver. The voltage across C5 is about 5V and is
supplied by the internal +5V supply when the SW pin voltage is low.
No Connect.
Supply Voltage. The MP2361 operates from a +4.75V to +23V unregulated
input. C1 is needed to prevent large voltage spikes from appearing at the input.
Switch. This connects the inductor to either IN through M1 or to GND through M2.
Ground. This pin is the voltage reference for the regulated output voltage. For
this reason care must be taken in its layout. This node should be placed outside
of the D1 to C1 ground path to prevent switching current spikes from inducing
voltage noise into the part.
Feedback. An external resistor divider from the output to GND, tapped to the FB
pin sets the output voltage. To prevent current limit run away during a short
circuit fault condition the frequency foldback comparator lowers the oscillator
frequency when the FB voltage is below 400mV.
Compensation. This node is the output of the transconductance error amplifier and the
input to the current comparator. Frequency compensation is done at this node by
connecting a series R-C to ground. See the compensation section for exact details.
Enable/UVLO. A voltage greater than 2.62V enables operation. Leave EN
unconnected for automatic startup. An Under Voltage Lockout (UVLO) function
can be implemented by the addition of a resistor divider from V
IN
to GND. For
complete low current shutdown it’s the EN pin voltage needs to be less than
700mV.
Soft-Start Pin. Connect SS to an external capacitor to program the soft-start. If
unused, leave it open.
