Compact Synchronous Buck Converters
ISL80020, ISL80020A, ISL80015, ISL80015A
The ISL80020, ISL80020A, ISL80015 and ISL80015A are highly
efficient, monolithic, synchronous step-down DC/DC converters
that can deliver up to 2A of continuous output current from a 2.7V
to 5.5V input supply. They use peak current mode control
architecture to allow very low duty cycle operation. They operate
at either 1MHz or 2MHz switching frequency, thereby providing
superior transient response and allowing for the use of small
inductors. They have excellent stability.
Features
• VIN range 2.7V to 5.5V
• IOUT maximum is 1.5A or 2A (see Table 1 on page 2)
• Switching frequency is 1MHz or 2MHz (see Table 1 on page 2)
• Overcurrent and short circuit protection
• Over-temperature/thermal protection
The ISL80020, ISL80020A, ISL80015 and ISL80015A integrate
very low rDS(ON) MOSFETs in order to maximize efficiency. In
addition, since the high-side MOSFET is a PMOS, the need for a
Boot capacitor is eliminated, thereby reducing external
component count. They can operate at 100% duty cycle
(at 1MHz).
The device is configured in PWM (pulse width modulation) for
fast transient response, which helps reduce the output noise
and RF interference.
• Negative current protection
• Power-good and enable
• 100% duty cycle (1MHZ)
• Internal soft-start and soft-stop
• VIN undervoltage lockout and VOUT overvoltage protection
• Up to 95% peak efficiency
Applications
These devices are offered in a space saving 8 pin 2mmx2mm
TDFN lead free package with exposed pad for improved thermal
performance. The complete converter occupies less than
64mm2 area.

PIN DESCRIPTION
The input supply for the power stage of the PWM regulator and the source for the internal linear regulator that provides
bias for the IC. Place a minimum of 10µF ceramic capacitance from VIN to GND and as close as possible to the IC for
decoupling.
Device enable input. When the voltage on this pin rises above 1.4V, the device is enabled. The device is disabled when
the pin is pulled to ground. When the device is disabled, a 100Ω resistor discharges the output through the PHASE pin.
See Figure 3, “FUNCTIONAL BLOCK DIAGRAM” on page 4 for details.
Connect pin 3 to EPAD
Power-good output is pulled to ground during the soft-start interval and also when the output voltage is below regulation
limits. There is an internal 5MΩ internal pull-up resistor on this pin.
Feedback pin for the regulator. FB is the negative input to the voltage loop error amplifier. The output voltage is set by
an external resistor divider connected to FB. In addition, the power-good PWM regulator’s power-good and undervoltage
protection circuits use FB to monitor the output voltage.
Connect NC pin to EPAD
Power and analog ground connections. Connect directly to the board GROUND plane.
Power stage switching node for output voltage regulation. Connect to the output inductor. This pin is discharged by an
100Ω resistor when the device is disabled. See Figure 3, “FUNCTIONAL BLOCK DIAGRAM” on page 4 for details.
The exposed pad must be connected to the PGND pin for proper electrical performance. Place as many vias as possible
under the pad connecting to the PGND plane for optimal thermal performance.
