VIN Under-Voltage Lockout (UVLO)
This pin also could be used as a digital input allowing
brightness control using a PWM signal from 100Hz to

ply transients from causing a restart. Once the input voltage exceeds the UVLO rising threshold, start-up begins.
In driving LED applications, the feedback voltage on FB
pin falls down if one of the LEDs, in series, is failed.
When the input voltage falls below the UVLO falling
threshold, the controller turns off the converter.
Meanwhile, the converter unceasingly boosts the output
voltage like a open-loop operation. Therefore, an over-

The APW7136 monitors the inductor current, flowing
through the N-channel MOSFET, and limits the current
peak at current-limit level to prevent loads and the
APW7136 from damaging during overload conditions.

Therefore, it is necessary to take further consideration
while choosing an adequate inductor. Mainly, the inductor value determines the inductor ripple current: larger

inductor value results in smaller inductor ripple current
and lower conduction losses of the converter. However,
larger inductor value generates slower load transient
response. A reasonable design rule is to set the ripple
current, ∆IL, to be 30% to 50% of the maximum average
inductor current, IL(AVG). The inductor value can be ob-

Layout Consideration
For all switching power supplies, the layout is an important step in the design; especially at high peak currents
and switching frequencies. If the layout is not carefully
Via To OVP
done, the regulator might show noise problems and duty
cycle jitter.

and the GND. Connecting the capacitor with VIN and

2. The inductor should be placed as close as possible to

well as the noise coupling into other circuits.
3. Since the feedback pin and network is a high imped-

ance circuit, the feedback network should be routed
away from the inductor. The feedback pin and feed-

back network should be shielded with a ground plane
or track to minimize noise coupling into this circuit.
4. A star ground connection or ground plane minimizes
ground shifts and noise is recommended.
