DESCRIPTION
V_IN
PGND
1, 2 The positive input voltage power node to the module, which is referenced to common GND.
3, 7, 8, 13,
14
The common ground connection for the V_I and V_O power connections.
V_OUT
I_SENSE
PWM
15, 16
11
4
The regulated positive power output with respect to GND.
Current sense output. The voltage level on this pin represents the average output current of the module.
The PWM input pin. It is a high impedance digital input that accepts 3.3-V or 5-V logic level signals up to 1 MHz.
FF
6
Current limit fault flag. The Fault signal is a 3.3-V digital output which is latched high after an over-current condition.
The Fault is reset after a complete PWM cycle without an over-current condition (falling edge of the PWM).
SRE
Synchronous Rectifier Enable. This pin is a high impedance digital input. A 3.3 V or 5 V logic level signals is used
5
to enable the synchronous rectifier switch. When this signal is high, the module will source and sink output current.
When this signal is low, the module will only source current.
AGND
T_SENSE
Thermal
Pad
9, 10
12
Analog ground return. It is the 0 V_dc reference for the control inputs.
Temperature sense output. The voltage level on this pin represents the temperature of the module.
This pad is electrically connected to PGND and is the primary thermal conduction cooling path for the module. This
pad should be soldered to a grounded copper pad on the host board. For optimum cooling performance, the
grounded copper pad should also be tied with multiple vias to the host board internal ground plane. See the Land
Pattern drawing for package ECY for recommended pad dimensions.
