Linear Technology Corporation introduced the LTC3872 H-level version, a compact 550kHz fixed-frequency boost DC/DC controller designed to operate within an extended temperature range of -40°C to 150°C. This device supports an input voltage range from 2.5V to 9.8V and can deliver output voltages up to 60V without requiring a sense resistor. When a sense resistor is used, the output voltage is limited only by external components.

The LTC3872 is capable of driving large N-channel MOSFETs, enabling high peak output currents. When powered by a 5V bias voltage, it can generate switching voltages as high as 60V, making it ideal for use in automotive, heavy equipment, and industrial control systems. Its robust design ensures reliable performance even under demanding conditions.

Based on a current-mode architecture, the LTC3872 offers cycle-by-cycle current limiting and excellent transient response. At light loads, the pulse skip mode reduces quiescent current to just 250µA, which significantly improves battery life in low-power applications. Additional features include internal soft-start, adjustable current limit, precision undervoltage lockout, and a tight ±1.6% reference accuracy across the full operating temperature range of -40°C to 150°C.

The LTC3872H is available in two compact packages: a thermally enhanced 2mm x 3mm DFN-8 and an 8-lead ThinSOTâ„¢ package. The unit price for a 1,000-piece order is $2.35.
