Pin Description

FUNCTION
NAME
1,2,3
VOUT
Output pin of the regulator. Connecting this pin to load and output capacitors (10µF at least) is
required for stability and improving transient response. The output voltage is programmed by the
resistor-divider connected to FB pin. The VOUT can provide 2A (max.) load current to loads.
During shutdown, the output voltage is quickly discharged by an internal pull-low MOSFET.
4
FB
Voltage Feedback Pin. Connecting this pin to an external resistor divider receives the feedback
voltage of the regulator.
5
POK
Power-OK signal output pin. This pin is an open-drain output used to indicate the status of output
voltage by sensing FB voltage. This pin is pulled low when output voltage is not within the
Power-OK voltage window.
6
EN
Active-high enable control pin. Applying and holding the voltage on this pin below the enable
voltage threshold shuts down the output. When re-enabled, the IC undergoes a new soft-start
process. When left this pin open, an internal pull-up current (5µA typical) pulls the EN voltage and
enables the regulator.
7,8,9
VIN
Main supply input pin for voltage conversions. A decoupling capacitor (≥10µF recommended) is
usually connected near this pin to filter the voltage noise and improve transient response. The
voltage on this pin is monitored for Power-On-Reset purpose
10
VCNTL
Bias voltage input pin for internal control circuitry. Connect this pin to a voltage source (+5V
recommended). A decoupling capacitor (1µF typical) is usually connected near this pin to filter the
voltage noise. The voltage at this pin is monitored for Power-On-Reset purpose.

capacitors) and low-ESR bulk capacitors (such as solid
tantalum, POSCap, and Aluminum electrolytic capacitors)
can all be used as output capacitors.
During load transients, the output capacitors which is depending on the stepping amplitude and slew rate of load
current, are used to reduce the slew rate of the current
seen by the APL5620 and help the device to minimize the
variations of output voltage for good transient response.
For the applications with large stepping load current, the
low-ESR bulk capacitors are normally recommended.
Decoupling ceramic capacitors must be placed at the load
and ground pins as close as possible and the impedance of the layout must be minimized.
Input Capacitor
The APL5620 requires proper input capacitors to supply
current surge during stepping load transients to prevent
the input voltage rail from dropping. Because the parasitic inductor from the voltage sources or other bulk capacitors to the VIN pin limit the slew rate of the surge
currents, more parasitic inductance needs more input
capacitance.
Ultra-low-ESR capacitors (such as ceramic chip
capacitors) and low-ESR bulk capacitors (such as solid
tantalum, POSCap, and Aluminum electrolytic capacitors
can all be used as an input capacitor of VIN. For most
applications, the recommended input capacitance of VIN
is 10µF at least. However, if the drop of the input voltage
is not cared, the input capacitance can be less than 10µF.
More capacitance reduces the variations of the supply
voltage on VIN pin.
