January 2020 DS12448 Rev 3 1/66 L99LD02 Automotive dual-phase boost DC/DC controller Datasheet - production data Features AEC-Q100 qualified General – 32-bit ST SPI communication v 4.1 – Stand-alone operation supported – QFN32L 5x5 with exposed pad – Timeout watchdog and Limp Home function Boost section – Wide input range: 3V to 28V operation – Device supply option from boost output – Adjustable boost output voltage - up to 80V – 10V Gate Driver supply for Standard-Level MOSFETs – Internal 10V LDO regulator – Fixed frequency architecture - programmable by SPI – Dither oscillator parameters as frequency modulation and deviation percentage - programmable by SPI – Peak current mode control with programmable Input Current Limitation – Constant voltage regulation – Adjustable Slope Compensation – Soft start – Multi-phase operation - up to 4-phase supported – SYNC I/O pin for multi-phase operation support – Adjustable clock distribution and phase shift – Programmable error amplifier gain – Fully configurable in Limp Home Protection and diagnostic – Boost functionality guaranteed in Cold Cranking – Input overcurrent protection - programmable by SPI – Thermal warning – Thermal shutdown – Overvoltage protection (OVP) Applications LED module applications. Description The L99LD02 is a two-phase, constant frequency, current mode boost controller able to drive N- channel power MOSFETs. Multi-phase operation is supported by SYNC I/O pin, providing the phase shifted clock signal. The boost controllers of more devices can be stacked, in order to operate in multi-phase for high power applications. Multi-phase operation reduces system filtering capacitance and inductance requirements. The operating frequency is configurable via SPI between 100kHz and 470kHz. Other features include an internal 10V LDO for the gate drivers, soft-start, device supply option from boost output and pre-configurable operation in Limp Home. www.st.com |
