FUNCTION
Externally Programmable Undervoltage Lockout. UVLO programs the input start voltage. Connect
UVLO to GND to disable the device.
Low-Frequency PWM Dimming Input/Error-Amplifier Inverting Input
Error-Amplifier Output. Connect the compensation components between DIM/FB and COMP in high-
accuracy LED current regulation.
Current-Sense Connection for Current Regulation. Connect to high side of sense resistor. An RC filter
may be necessary to eliminate leading-edge spikes.
Power-Supply Ground
External n-Channel MOSFET Gate Connection
Gate-Drive Supply. Internally regulated down from IN. Decouple with a 10nF or larger capacitor to GND.
IC Supply. Decouple with a 10nF or larger capacitor to GND. For bootstrapped operation (MAX16801),
connect a startup resistor from the input supply line to IN. Connect the bias winding supply to this point
(see Figure 5). For the MAX16802, connect IN directly to a +10.8V to +24V supply.
Detailed Description
The MAX16801/MAX16802 family of devices is intend-
ed for constant current drive of high-brightness (HB)
LEDs used in general lighting and display applications.
They are specifically designed for use in isolated and
nonisolated circuit topologies such as buck, boost, fly-
back, and SEPIC, operating in continuous or discontin-
uous mode. Current mode control is implemented with
an internally trimmed, fixed 262kHz switching frequen-
cy. A bootstrap UVLO with a large hysteresis (11.9V),
very low startup current, and low operating current
result in an efficient universal-input LED driver. In addi-
tion to the internal bootstrap UVLO, these devices also
offer programmable input startup voltage programmed
through the UVLO/EN pin. The MAX16801 is well suited
for universal AC input (rectified 85VAC to 265VAC) dri-
vers. The MAX16802 is well suited for low input voltage
(10.8VDC to 24VDC) applications.
The MAX16801/MAX16802 regulate the LED current by
monitoring current through the external MOSFET cycle
by cycle.
