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.
8
The inhibit pin is a negative logic input that is referenced to AGND. Applying a low-level signal to 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 complete PWM cycles without an over-current condition (third rising 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 to
10 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.
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 1 MHz.
VBIAS
12 Bias voltage supply required to power internal circuitry. For optimal performance connect VBIAS to V_I.
(1) Denotes negative logic: High = Normal operation, Low = Function active
