Detailed Description

Automotive-grade high-voltage PWM controller for dual-ended power topologies

Supports push-pull, half-bridge, full-bridge, and two-switch forward converters

Integrated high-voltage startup regulator, precision reference, error amplifier, oscillator with sync, current-sense and slope compensation, soft-start, UVLO/OVLO, and thermal protection

Designed for wide-input, isolated and non-isolated DC-DC power supplies in automotive, industrial, and telecom systems

The “Q” grade targets AEC-Q100–type reliability for automotive environments

Key Features

High-voltage startup regulator (eliminates external high-value start resistors)

Dual alternating PWM outputs for symmetrical drive (ideal for push-pull/half-bridge)

Programmable switching frequency (external resistor/capacitor) and external clock synchronization

Cycle-by-cycle current limit with slope compensation for stable current-mode control

Programmable soft-start for controlled inrush and reduced stress on power components

Undervoltage and overvoltage lockout with hysteresis (UVLO/OVLO) and brownout handling

Precision internal reference for tight regulation and low drift

Low standby/operating current to improve light-load efficiency

Leading-edge blanking and noise filtering on current-sense input

Thermal shutdown and comprehensive fault handling

Key Advantages

Flexible: one controller supports multiple topologies (fewer part numbers to manage)

Robust: integrated protections (UVLO, OVP, current limit, thermal) safeguard the power stage

Efficient: current-mode control with slope compensation improves dynamic response and reduces overshoot

EMI-friendly: clock sync makes spread-spectrum or system-frequency alignment easy

Space-saving: on-chip startup regulator and reference reduce external BOM

Automotive-ready: “Q” grade option for high-reliability environments

Packaging

Shipment type: Tape & Reel (suffix X), ideal for automated SMT lines

Package family: 16-pin small-outline controller package per TI “MT” code (check the TI package drawing for exact outline, land pattern, and mechanical data)

Case/pin count: 16 leads; typical pins include VIN (HV start), VCC, VREF, OUTA, OUTB, CS, RT/SYNC, SS, COMP, UVLO/OVP, and GND

Materials: RoHS-compliant, lead-free, halogen-free mold compound and matte-tin plating (per TI standard)

Moisture/reflow: JEDEC-compliant MSL and lead-free reflow profile (verify exact MSL level in the datasheet/package notes before assembly)

Thermal: low thermal impedance when using recommended PCB copper and exposed pad/thermal vias (see datasheet for RθJA/RθJC and layout guidance)

Electrical at a glance: integrated high-voltage startup regulator, logic-level gate outputs sized to drive external MOSFET drivers or small FETs, wide programmable frequency range (verify limits in datasheet), precision reference for tight regulation

Reel/handling: standard 13-inch reel; factory pack typically in the 2k–3k range (our current stock is 2288 units)

Date code: 1640+ (contact us if you require specific DC/lot traceability)
