Микросхемы и комплектующие LT8602ILXE#PBF

Импульсный DC/DC стабилизатор , регулируемый, синхронный, 4 выхода, 3В до 42В вход, 42В/2.5А выход

The LT8602ILXE#PBF from Linear Technology is a 42V quad monolithic synchronous step-down regulator in 48 pin (7mm × 7mm) plastic eLQFP package. It is a quad channel, current mode, monolithic buck switching regulator with a programmable power-on reset. All regulators are synchronized to a single oscillator with an adjustable frequency from 250KHz to 2.2MHz. LT®8602 can be configured for micropower Burst Mode® operation or pulse-skipping operation at light load. Micropower operation results in quiescent current of 30µA. The high voltage channels are synchronous buck regulators that operate from an input of 3V to 42V. The output currents are up to 1.5A (OUT1) and 2.5A (OUT2). The low voltage channels operate from an input of 2.6V to 5.5V. Internal synchronous power switches provide high efficiency with output currents up to 1.8A. The LT8602 uses a 2-phase clock with channels 1 and 3 operating 180° from channels 2 and 4 to reduce input ripple current on both HV and LV inputs.

• Flexible power supply system providing four outputs with a wide input range
• Output ripple is less than 15mV
• Programmable power-on reset
• Power good indicators
• 2-phase clock reduces input current ripple
• Thermal shutdown provides additional protection
• All channels have cycle-by-cycle current limit, providing protection against shorted outputs
• Operating temperature range from -40°C to 125°C
