Thermal Overload Protection
Thermal shutdown circuit will disable device
operation when the junction temperature exceeds
approximately 150ºC. After a thermal shutdown
event, when the junction temperature drops by
approx 20ºC, the converter will re-start with a
normal soft-start.
Application Information
Output Voltage Programming and Loop
Compensation
The EN2360QI uses a Type IV Voltage Mode
compensation network. Type IV Voltage Mode
control is a proprietary Enpirion control scheme that
maximizes control loop bandwidth to deliver
excellent load transient responses and maintain
output regulation with pin point accuracy. For ease
of use, most of this network has been customized
and is integrated within the device package. The
EN2360QI output voltage is programmed using a
simple resistor divider network (R
feedback voltage at VFB is nominally 0.6V. R
predetermined based on Table 5 and R
calculated based on Figure 10. The values
recommended for C
the external compensation of the EN2360QI. It will
vary with each PVIN and VOUT combination to
optimize on performance. The EN2360QI solution
can be optimized for either smallest size or highest
performance. Please see Table 5 for a list of
recommended R

Input Under-Voltage Lock-Out (UVLO)
Internal circuits ensure that the converter will not
start switching until the input voltage is above the
specified minimum voltage. Hysteresis, input de-
glitch and output leading edge blanking ensures
high noise immunity and prevents false UVLO
triggers.

rated. Y5V or equivalent dielectric formulations
must not be used as these lose too much
capacitance with frequency, temperature and
bias voltage. In some applications, lower value
capacitors are needed in parallel with the larger,
capacitors in order to provide high frequency

Output Capacitor Selection
As seen from Table 5, the EN2360QI has been
optimized for use with one 100µF/1206 plus two
47µF/1206 output capacitors for best performance.
For the smallest solution size configuration see
Table 5. Low ESR ceramic capacitors are required
with X5R or X7R rated dielectric formulation. Y5V
or equivalent dielectric formulations must not
be used as these lose too much capacitance
with frequency, temperature and bias voltage.

reactance.
Placing output capacitors in parallel reduces the
impedance and will hence result in lower ripple
voltage.
