PIN FUNCTIONS (See Package Description for Pin Assignment)
f SET (Pin B12): Frequency Set Internally to 1MHz. An
external resistor can be placed from this pin to ground
to increase frequency. See the Applications Information
section for frequency adjustment.
V FB (Pin F12): The Negative Input of the Error Ampli-
fier. Internally, this pin is connected to V OUT_LCL with a
60.4k precision resistor. Different output voltages can be
programmed with an additional resistor between V FB and
SGND pins. See the Applications Information section.
MARG0 (Pin C12): This pin is the LSB logic input for the
margining function. Together with the MARG1 pin it will
determine if margin high, margin low or no margin state
is applied. The pin has an internal pull-down resistor of
50k. See the Applications Information section.
MARG1 (Pin D12): This pin is the MSB logic input for the
margining function. Together with the MARG0 pin it will
determine if margin high, margin low or no margin state
is applied. The pin has an internal pull-down resistor of
50k. See the Applications Information section.
SGND (Pin H12): Signal Ground. This pin connects to
PGND at output capacitor point.
8
COMP (Pin A11): Current Control Threshold and Error
Amplifier Compensation Point. The current comparator
threshold increases with this control voltage. The voltage
ranges from 0V to 2.4V with 0.7V corresponding to zero
sense voltage (zero current).
PGOOD (Pin G12): Output Voltage Power Good Indicator.
Open-drain logic output that is pulled to ground when the
output voltage is not within ±10% of the regulation point,
after a 25μs power bad mask timer expires.
RUN (Pin A10): Run Control Pin. A voltage above 1.9V
will turn on the module, and when below 1V, will turn
off the module. A programmable UVLO function can be
accomplished by connecting to a resistor divider from
V IN to ground. See Figure 1. This pin has a 5.1V Zener to
ground. Maximum pin voltage is 5V. Limit current into the
RUN pin to less than 1mA.
V OUT_LCL (Pin L12): V OUT connects directly to this pin to
bypass the remote sense amplifier, or DIFFV OUT connects
to this pin when the remote sense amplifier is used.
V OUT_LCL can be connected to V OUT on the LTM4603-1.
V OUT is internally connected to V OUT_LCL through 50 W in
the LTM4603-1.
