TERMINAL FUNCTIONS
TERMINAL
DESCRIPTION
NAME
NO.
V_I
GND
1 The positive input voltage power node to the module, which is referenced to common GND.
2
3 ^{This is the common ground connection for the VI and VO power connections.}
V_O
TEMP
4 The regulated positive power output with respect to GND.
5 Temperature sense output. The voltage level on this pin represents the temperature of the module.
IOUT
6 Current sense output. The voltage level on this pin represents the average output current of the module.
AGND
INH ⁽¹⁾
7 Analog ground return. It is the 0 V_dc reference for the control inputs.
The inhibit pin is an open-collector/drain, negative logic input that is referenced to AGND. Applying a low-level signal to
8 this pin disables the module and turns off the output voltage. A 10 kΩ pull-up to 3.3 V or 5 V is required if the INH
signal is not used.
FAULT
9
Current limit 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 two rising edges on the PWM pin.
SRE
10
Synchronized Rectifier Enable. This pin is a high impedance digital input. A 3.3 V or 5 V logic level signals is used to
enable the synchronous rectifier switch.
PWM
11
This is the PWM input pin. It is a high impedance digital input that accepts 3.3 V or 5 V logic level signals up to 500
MHz.
VBIAS
12 Bias voltage supply required to power internal circuitry. For optimal performance connect VBIAS to V_I.
(1) Denotes negative logic: Open = Normal operation, Ground = Function active
