Product Overview
LT®3759 is a wide input range, current mode, DC/DC controller which is capable of regulating either positive or negative output voltages from a single feedback pin. It can be configured as a boost, SEPIC or inverting converter. This drives a low side external N-channel power MOSFET. An internal LDO regulator draws power from VIN or DRIVE to provide up to a 4.75V supply for the gate driver. The operating frequency of this can be set over a 100KHz to 1MHz range with an external resistor, or can be synchronized to an external clock using the SYNC pin. This features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. A window comparator on the FBX pin reports via the active-low PGOOD pin, providing output voltage status indication. Typical applications are datacom and industrial boost, SEPIC and inverting converters, distributed power supplies, portable electronic equipment, automotive.
- Positive or negative output voltage programming with a single feedback pin
- Accurate 50mV SENSE threshold voltage, programmable soft-start
- Programmable operating frequency (100KHz to 1MHz) with one external resistor
- Synchronizable to an external clock, low shutdown current
1µA - INTVCC regulator supplied from VIN or DRIVE
- Programmable input undervoltage lockout with hysteresis
- VIN operating voltage range from 1.6 to 42V (TA=25°C, VIN=12V, EN/UVLO=12V, INTVCC=4.75V)
- VIN operating IQ is 450µA
- 12-lead plastic MSOP package
- Temperature rating range from –40°C to 125°C
