The MAX25610A/MAX25610B are fully synchronous LED drivers that provide constant output current to drive high-power LEDs. The MAX25610A/MAX25610B integrate two 60mΩ power MOSFETs for synchronous operation, minimizing external components. Flexible configuration supports buck, inverting buck-boost, and boost conversion. The devices incorporate current-mode control that provides fast transient response and eases loop stabilization. The MAX25610A/MAX25610B include cycle by cycle current limiting, output overvoltage protection (OVP), open-string protection, output short-circuit protection (SCP), and thermal shutdown. In LED driver applications, the MAX25610A/MAX25610B provide analog dimming of the LED current through the REFI pin, and PWM dimming through the PWMDIM pin. Switching is enabled when PWMDIM is high, and disabled with both MOSFETs off when PWMDIM is low. Analog programming of the PWMDIM pin enables the built-in digital dimming function, with dimming frequency selected by the PWMFRQ pin. The MAX25610A/MAX25610B include two 5V regulators. A regulated 5V between VCC and AGND is used for IC bias, REFI and PWMFRQ programming. Another low current regulated 5V between VEE and INN is used for analog PWMDIM and FLT pullup. Both PWMDIM and FLT reference INN for easy system interface. Switching frequency is internally set at 400kHz for the MAX25610A and 2.2MHz for the MAX25610B. The devices have built-in spread spectrum to reduce EMI noise. External and internal current sense are supported, with ±3% and ±6% respective LED current accuracy. The MAX25610A/MAX25610B are well-suited for automotive applications requiring high voltage input and can withstand load dump events up to 40V. The devices can also be used as a DC-DC converter using the FB input as feedback for the output voltage divider. The MAX25610A/MAX25610B are available in thermally enhanced 16-pin TSSOP-EP and 16-pin TQFN packages. They are specified to operate over the -40°C to +125°C automotive temperature range.
