DESCRIPTION
NAME
NO.
CLK/LEB
4
O
Clock/leading-edge blanking. Output of the internal oscillator.
Capacitor timing. Timing capacitor connection for oscillator frequency programming. The timing capacitor
CT
6
I
should be connected to the device ground using minimal trace length.
EAOUT
3
O
Output of the error amplifier for compensation
GND
10
Analog ground return
ILIM
9
I
Input to the current-limit comparator
INV
1
I
Inverting input to the error amplifier
NI
2
I
Noninverting input to the error amplifier
OUTA
11
O
High-current totem-pole output A of the on-chip drive stage
OUTB
14
O
High-current totem-pole output B of the on-chip drive stage
PGND
12
Ground return for the output driver stage
Noninverting input to the PWM comparator, with 1.25-V internal input offset. In voltage-mode operation, this
RAMP
7
I
serves as the input voltage feed-forward function by using the CT ramp. In peak current mode operation,
this serves as the slope compensation input.
RT
5
I
Resistor timing. Timing resistor connection for oscillator frequency programming.
SS
8
I
Soft-start. SS also doubles as the maximum duty cycle clamp.
Power-supply for the output stage. This pin should be bypassed with a 0.1-mF monolithic ceramic low-ESL
VC
13
capacitor with minimal trace lengths.
Power supply for the device. This pin should be bypassed with a 0.1-mF monolithic ceramic low-ESL
VCC
15
O
capacitor with minimal trace lengths.
5.1-V reference. For stability, the reference should be bypassed with a 0.1-mF monolithic ceramic low-ESL
VREF
16
capacitor and minimal trace length to the ground plane.
