Product Overview
The MAX16838AUP/V+ is an integrated, 2-channel, high brightness LED driver with high voltage boost and SEPIC controller in 20 pin TSSOP package. It integrates both DC to DC switching boost regulator and two 150mA current sinks. A current mode switching DC to DC controller provides necessary voltage to both strings of HB LEDs. The MAX16838 accepts a wide 4.75V to 40V input voltage range and directly withstands automotive load dump events. The wide input range allows powering HB LEDs for small to medium sized LCD displays in automotive and display backlight applications. An internal current mode switching DC to DC controller supports boost or SEPIC topologies and operates in an adjustable frequency range between 200KHz and 2MHz. The MAX16838 can be combined with MAX15054 to achieve buck-boost LED driver with two integrated current sinks. The channel current is adjustable from 20mA to 150mA using an external resistor.
- 4.75V to 40V or 5V ±10% input operating voltage range (internal LDO on)
- Automotive AEC-Q100 grade 1 qualified, operating temperature range from -40°C to +125°C
- Adaptive output voltage adjustment scheme minimizes power dissipation in LED current sink paths
- Dropout voltage of 0.11V at VIN = 4.75V, IOUT = 30mA and output voltage of 5V
- Boost or SEPIC power topologies for maximum flexibility
- Quiescent supply current of 3.1mA and standby supply current of 15.5μA
- 5000:1 PWM dimming at 200Hz, duty cycle of 90% at fSW = 200KHz and 85% at fSW = 2000KHz
- LED open/short detection and protection, output overvoltage and overtemperature protection
- Programmable LED current foldback at lower input voltages and open-drain fault indicator output
- Current mode control switching stage with internal slope compensation
