any ambient temperature is calculated by PD (MAX) = (TJ

REGULATOR WITH INTEGRATED INDUCTOR IN ULTRA-SMALL 2X2X0.9MM QFN PACKAGE
When the loading becomes lighter, the ripple of
OPERATION
the output voltage is bigger and drives the error
amplifier output (EAO) lower. When the EAO
reaches the internal low threshold, it is clamped
at that level, and the MPM3804 enters sleep
mode. During sleep mode, the valley of the FB
voltage is regulated to the internal reference
voltage, and the average output voltage is
slightly higher than the output voltage in
discontinuous conduction mode (DCM) or
continuous conduction mode (CCM). The on-
time pulse in sleep mode is around 40% larger
than that in DCM or CCM. Figure 3 shows the
average FB voltage relationship with the
internal reference in sleep mode.
The MPM3804 uses a constant-on-time (COT)
control with input voltage feed-forward to
stabilize the switching frequency over the full
input range. The MPM3804 achieves 0.6A of
continuous output current from a 2.3V to 5.5V
input voltage range with excellent load and line
regulation. The output voltage can be regulated
as low as 0.6V.
Constant-On-Time (COT) Control
Compared to fixed-frequency PWM control,
constant-on-time (COT) control offers a simpler
control loop and faster transient response. By
using an input voltage feed-forward, the

switching frequency across the input and output
voltage ranges. The switching pulse on time
can be estimated with Equation (1):

When the MPM3804 is in sleep mode, the
average output voltage is higher than the

increases, the PWM switching
period
decreases to keep the output voltage regulated,
and the output voltage ripple decreases
relatively. Once the EAO is higher than the
internal low threshold, the MPM3804 exits sleep
mode and enters DCM or CCM depending on
the load. In DCM or CCM, the error amplifier
regulates the average output voltage to the
internal reference (see Figure 4).
Sleep-Mode Operation
The MPM3804 uses sleep mode to achieve
high efficiency at extremely light loads. In sleep
mode, most of the circuit blocks are turned off
except for the error amplifier and PWM
comparator. Therefore, the operation current is
reduced to a minimal value (see Figure 2).

The MPM3804 has an open drain and requires
an external pull-up resistor (100kΩ~500kΩ) for
the power good (PG) indicator. When VFB is
within -10% of regulation voltage, VPG is pulled
up to VIN by the external resistor. If VFB
exceeds the -10% window, the internal
MOSFET pulls PG to ground. The MOSFET
has a maximum RDS(ON) of less than 100Ω.

The MPM3804 uses a ZCD to determine when
the inductor current starts to reverse. When the
inductor current reaches the ZCD threshold, the
low-side switch is turned off.
Current Limit
The MPM3804 has a 1.3A, high-side, switch-
current limit, typically. When the high-side
switch reaches its current limit, the MPM3804
remains in hiccup mode until the current drops.
This prevents the inductor current from
continuing to rise and damaging components.
AAM mode together with the ZCD circuit makes
the MPM3804 work in DCM at light load
continuously, even if VOUT is close to VIN.
Short Circuit and Recovery
Enable (EN)
The MPM3804 enters short-circuit protection
(SCP) mode when it reaches the current limit
and attempts to recover with hiccup mode. The
MPM3804 disables the output power stage,
discharges the soft-start capacitor, and
attempts to soft start automatically. If the short-
circuit condition remains after the soft start
ends, the MPM3804 repeats this cycle until the
short circuit is removed and the output rises
back to regulation levels.
When the input voltage is greater than the
under-voltage lockout (UVLO) threshold
(typically 2V), the MPM3804 can be enabled by
pulling EN higher than 1.2V. Leave EN floating
or pull EN down to ground to disable the
MPM3804. There is an internal 1MΩ resistor
from EN to ground.
When the device is disabled, the part goes into
output discharge mode automatically. The
internal discharge MOSFET provides a resistive
discharge path for the output capacitor.
Soft Start (SS)
The MPM3804 has a built-in soft start (SS) that
ramps up the output voltage at a controlled slew
rate to avoid overshooting at start-up. The soft-
start time is about 0.5ms, typically.

The external resistor divider sets the output

reduce the VOUT leakage current, typically
