STEP-DOWN DC/DC CONVERTER
FUNCTIONAL DESCRIPTION
Input Capacitor Selection
General Description
The input capacitor reduces peak currents and
noise induced upon the voltage source. A 2.2µF
ceramic input capacitor is recommended for most
applications.
REG1 is a fixed-frequency, current-mode, synchro-
nous PWM step-down converters that achieves a
peak efficiency of up to 97%. REG1 is capable of
supplying up to 350mA of output current and oper-
ates with a fixed frequency of 1.6MHz, minimizing
noise in sensitive applications and allowing the use
of small external components. REG1 is available
with a variety of standard and custom output volt-
ages, as well as an adjustable output voltage option.
Output Capacitor Selection
For most applications, a 10µF ceramic output ca-
pacitor is recommended. Although REG1 was de-
signed to take advantage of the benefits of ceramic
capacitors, namely small size and very-low ESR,
low-ESR tantalum capacitors can provide accept-
able results as well.
100% Duty Cycle Operation
REG1 is capable of operating at up to 100% duty
cycle. During 100% duty-cycle operation, the
high-side power MOSFET is held on continuously,
providing a direct connection from the input to the
output (through the inductor), ensuring the lowest
possible dropout voltage in battery-powered appli-
cations.
Inductor Selection
REG1 utilizes current-mode control and a proprie-
tary internal compensation scheme to simultane-
ously simplify external component selection and
optimize transient performance over its full operat-
ing range. REG1 was optimized for operation with a
3.3µH inductor, although inductors in the 2.2µH to
4.7µH range can be used. Choose an inductor with
a low DC-resistance, and avoid inductor saturation
by choosing inductors with DC ratings that exceed
the maximum output current of the application by at
least 30%.
Synchronous Rectification
REG1 features an integrated n-channel synchro-
nous rectifier, which maximizes efficiency and mini-
mizes the total solution size and cost by eliminating
the need for an external rectifier.
Enabling and Disabling REG1
Thermal Shutdown
REG1 is enabled or disabled using ON1. Drive ON1
to a logic-high to enable REG1. Drive ON1 to a
logic-low to disable REG1, reducing supply current
to less than 1µA
The ACT8332 integrates thermal shutdown protec-
tion circuitry to prevent damage resulting from ex-
cessive thermal stress, as may be encountered un-
der fault conditions. This circuitry disables all regu-
lators if the ACT8332 die temperature exceeds
160°C, and prevents the regulators from being en-
abled until the IC temperature drops by 20°C (typ).
Soft-Start
REG1 includes internal soft-start circuitry, and en-
abled its output voltage tracks an internal 80µs soft-
start ramp so that it powers up in a monotonic man-
ner that is independent of loading.
Output Voltage Programming
Figure 4 shows the feedback network necessary to
set the output voltage when using the adjustable
output voltage option. Select components as fol-
lows: Set RFB2 = 51Kꢀ, then calculate RFB1 using
the following equation:
Compensation
REG1 utilizes current-mode control and a proprie-
tary internal compensation scheme to simultane-
ously simplify external component selection and
optimize transient performance over its full operat-
ing range. No compensation design is required,
simply follow a few simple guidelines described be-
low when choosing external components.

PCB Layout Considerations
High switching frequencies and large peak currents
make PC board layout an important part of step-
down DC/DC converter design. A good design mini-
mizes excessive EMI on the feedback paths and volt-
age gradients in the ground plane, both of which can
result in instability or regulation errors. Step-down
DC/DCs exhibit discontinuous input current, so the
input capacitors should be placed as close as possi-
ble to the IC, and avoiding the use of vias if possible.
The inductor, input filter capacitor, and output filter
capacitor should be connected as close together as
possible, with short, direct, and wide traces. The
ground nodes for each regulator's power loops
should be connected at a single point in a star-
ground configuration, and this point should be con-
nected to the backside ground plane with multiple
vias. For fixed output voltage options, connect the
output node directly to the FB1 pin. For adjustable
output voltage options, connect the feedback resis-
tors and feed-forward capacitor to the FB1 pin
through the shortest possible route. In both cases,
the feedback path should be routed to maintain suffi-
cient distance from switching nodes to prevent noise
injection. Finally, the exposed pad should be directly
connected to the backside ground plane using multi-
ple vias to achieve low electrical and thermal resis-
tance.

LOW-DROPOUT LINEAR REGULATORS
FUNCTIONAL DESCRIPTION
A good design places input and output capacitors
as close to the LDO inputs and output as possible,
General Description
REG2 and REG3 are low-noise, low-dropout linear
regulators (LDOs) that are optimized for low-noise
and high-PSRR operation, achieving more than
60dB PSRR at frequencies up to 10kHz.
and utilizes a star-ground configuration for all regu-
lators to prevent noise-coupling through ground.
Output traces should be routed to avoid close prox-
imity to noisy nodes, particularly the SW nodes of
the DC/DCs.
Output Current Capability
REG2 and REG3 each supply 360mA of load cur-
rent. Excellent performance is achieved over each
regulator's entire load current ranges.
Output Current Limit
In order to ensure safe operation under over-load
conditions, each LDO features current-limit circuitry
with current fold-back. The current-limit circuitry
limits the current that can be drawn from the output,
providing protection in over-load conditions. For
additional protection under extreme over current
conditions, current-fold-back protection reduces the
current-limit by approximately 30% under extreme
overload conditions.
Enabling and Disabling the LDOs
REG2 and REG3 is enabled or disabled using ON1
and ON3. Drive ON1 and ON3 to a logic-high to
enable REG2 and REG3. Drive ON1 and ON3 to a
logic-low to disable REG2 and REG3, reducing
supply current to less than 1µA.
Output Capacitor Selection
REG2 and REG3 each require only a small ceramic
capacitor for stability. For best performance, each
output capacitor should be connected directly be-
tween the OUT2 and OUT3 and G pins as possible,
with a short and direct connection. To ensure best
performance for the device, the output capacitor
should have a minimum capacitance of 1µF, and
ESR value between 10mꢀ and 200mꢀ. High quality
ceramic capacitors such as X7R and X5R dielectric
types are strongly recommended.
PCB Layout Considerations
The ACT8332’s LDOs provide good DC, AC, and
noise performance over a wide range of operating
conditions, and are relatively insensitive to layout
considerations. When designing a PCB, however,
careful layout is necessary to prevent other circuitry
from degrading LDO performance.
