PIN FUNCTION DESCRIPTION
Pin
Function
Description
1
Drive Output
This output directly drives the gate of a power MOSFET. Peak currents up to 1.0 A are
sourced and sinked by this pin.
2
Drive Ground
This pin is a separate power ground return that is connected back to the power source. It is
used to reduce the effects of switching transient noise on the control circuitry.
3
Ramp Input
A voltage proportional to the inductor current is connected to this input. The PWM uses this
information to terminate output switch conduction.
4
Sync/Inhibit Input
A rectangular waveform applied to this input will synchronize the Oscillator and limit the
maximum Drive Output duty cycle. A dc voltage within the range of 2.0 V to VCC will inhibit
the controller.
5
RT/CT
The free–running Oscillator frequency and maximum Drive Output duty cycle are
programmed by connecting resistor RT to Vref 2.5 V and capacitor CT to Ground. Operation
to 300 kHz is possible.
6
Vref 2.50 V
This output is derived from Vref 1.25 V. It provides charging current for capacitor CT through
resistor RT.
7
Ground
This pin is the control circuitry ground return and is connected back to the source ground.
8
Vref 1.25 V
Error Amp Noninverting Input
This output furnishes a voltage reference for the Error Amplifier noninverting input.
9
This is the noninverting input of the Error Amplifier. It is normally connected to the 1.25 V
reference.
10
Error Amp Inverting Input
This is the inverting input of the Error Amplifier. It is normally connected to the switching
power supply output through a resistor divider.
11
Feedback/PWM Input
This pin is available for loop compensation. It is connected to the Error Amplifier and
Soft–Start Buffer outputs, and the Pulse Width Modulator input.
12
CSoft–Start
A capacitor CSoft–Start is connected from this pin to Ground for a controlled ramp–up of peak
inductor current during startup.
13
Start/Run Output
This output controls the state of an external bootstrap transistor. During the start mode,
operating bias is supplied by the transistor from Vin. In the run mode, the transistor is
switched off and bias is supplied by an auxiliary power transformer winding.
14
VCC
This pin is the positive supply of the control IC. The controller is functional over a minimum
VCC range of 4.2 V to 12 V.
