MAX16801A, MAX16801B, MAX16802A, MAX16802B Offline And DC-DC PWM Controllers For High-Brightness LED Drivers

The MAX16801A B MAX16802A B high-brightness (HB) LED Driver 4d4 -control ICs contain all the circuitry required for the design of wide-input-voltage-range LED Drivers for general lighting and Display applications. The MAX16801 is well suited for universal input (rectified 85VAC to 265VAC) LED Drivers while the MAX16802 is intended for low-input-voltage (10.8VDC to 24VDC) LED drivers.
When the LED current needs to be tightly regulated, an additional on-board error Amplifier with 1% accurate reference CAN be utilized. A wide dimming range CAN be implemented by using low-frequency PWM dimming.
The MAX16801/MAX16802 feature an input undervoltage lockout (UVLO) for programming the input-supply start voltage, and to ensure proper operation during brownout conditions. The MAX16801 has an internal-bootstrap undervoltage lockout circuit with a large hysteresis that simplifies offline LED Driver designs. The MAX16802 does not have this internal bootstrap circuit and CAN be biased directly from a +12V rail.
The 262kHz fixed switching frequency is internally trimmed, allowing for optimization of the magnetic and Filter components, resulting in a compact, cost-effective LED Driver The MAX16801A MAX16802A are offered with 50% maximum duty 4f2 cycle.The MAX16801B MAX16802B are offered with 75% maximum duty cycle. These devices are available in an 8-pin MAX package and operate over the -40C to +85C temperature range.
