Product Overview
LT®3496 is a triple-output DC/DC converter designed to operate as a constant-current source and is ideal for driving LED. This works in buck, boost, or buck-boost mode. This uses a fixed frequency, current mode architecture resulting in stable operation over a wide range of supply and output voltages. A frequency adjust pin allows the user to program switching frequency between 330KHz and 2.1MHz to optimize efficiency and external component size. This supports 3000:1 dimming control on each channel. Each of the three regulators is independently operated by that channel’s PWM signal. The PWM feature allows precise adjustment of the colour mixing or dimming ratio of the LED source. Each of the three channels has a built-in gate driver to drive an external LED-disconnect P-channel MOSFET, allowing a high dimming range. Application includes RGB lighting, billboards, and large displays, automotive and avionic lighting, and constant current sources.
- True colour PWM™ dimming delivers up to 3000:1 dimming ratio
- Built-in gate driver for PMOS LED disconnect
- Operates in buck, boost, buck-boost modes
- VIN operation voltage range from 3 to 30V (TA = 25°C)
- Typical switching frequency is 2100KHz (fADJ = 1.5V, TA = 25°C)
- Typical gate turn-on delay is 110ns (CLOAD = 300pF, CAP1, CAP2, CAP3 = 40V, TA = 25°C)
- Typical PWM1, PWM2, PWM3 pin current is 160µA (current into pin, TA = 25°C)
- Typical SW1, SW2, SW3 current limit is 1000mA (TA = 25°C)
- 28-lead plastic QFN package
- Temperature rating range from -40°C to 125°C
