Detailed Description

750 mA adjustable step-down (buck) DC-DC regulator in a thin SOT-23-6 package. Wide 3 V to 18 V input range, 1.6 MHz fixed switching frequency for very small inductors and capacitors. Non-synchronous topology requires an external Schottky diode. Outputs 1.25 V to 16 V. Designed for compact, efficient point-of-load power in space-limited systems

Key Features

Input voltage 3 V to 18 V wide range

Output current up to 750 mA

Adjustable output 1.25 V to 16 V with resistor divider

Fixed 1.6 MHz switching frequency for small solution size

Buck topology, positive output

Non-synchronous rectification using an external Schottky diode

Enable pin for on/off control

Internal protection features including cycle-by-cycle current limit and thermal shutdown

Surface-mount TSOT-23-6 thin package

ROHS3 compliant lead-free construction

Operating junction temperature range −40°C to +125°C

Key Advantages

Very small power solution thanks to high 1.6 MHz frequency and TSOT-23-6 package

Simple design with few external parts and internal compensation

Flexible output voltage to cover many rails from 1.25 V up to 16 V

High efficiency across a wide input range for battery or industrial rails

Proven TI reliability and broad ecosystem of design resources

Packaging

Shipment format Tape and Reel TR for automated SMT assembly

Package case SOT-23-6 Thin TSOT-23-6 SOT-23-THIN

Mounting type Surface Mount

Approximate body size about 2.9 mm x 1.6 mm, low profile thin height typical of TSOT-23-6

Leads 6 pins with standard SOT-23-6 footprint and 0.95 mm pitch

Typical pin functions SW switch node, VIN input, FB feedback, EN enable, GND ground, BST boot/boost for gate drive

Materials mold-encapsulated epoxy body, Pb-free matte tin plated leads, halogen-free per TI RoHS3 compliance

Moisture sensitivity level typically MSL 1 for SOT-23 class parts store and handle per JEDEC guidelines

Thermal characteristics junction temperature −40°C to +125°C TJ, thermal resistance depends on PCB copper and layout see datasheet package drawing and thermal data for θJA guidance

Electrical properties per device ratings input 3 V to 18 V, output up to 750 mA, 1.6 MHz switching, adjustable 1.25 V to 16 V, non-synchronous requires external Schottky diode and inductor sized for load and ripple targets
