What are the key features of TC4627EPA?
- 1.5 A peak gate drive current enabling fast MOSFET switching transitions under 20 ns for reduced switching losses in DC-DC converters
- High-side driver with bootstrap boost supply support for N-channel MOSFET driving above the supply rail in half-bridge and buck topologies
- Non-inverting buffer-based gate driver in 8-pin PDIP for easy prototyping and compatibility with through-hole power stage designs
What is TC4627EPA used for?
The TC4627EPA is used in DC-DC buck and half-bridge converter power stages to drive N-channel MOSFETs with 1.5 A of gate current for fast switching transitions. Its boost supply input supports high-side N-channel MOSFET configurations where the gate must swing above the drain supply rail during turn-on. The device also serves motor control pre-driver stages and solenoid valve drivers in industrial automation where robust gate drive and noise immunity are required.

Frequently Asked Questions
What peak gate drive current does TC4627EPA provide, and how does this affect MOSFET switching speed in a buck converter?
The TC4627EPA sources and sinks up to 1.5 A of peak gate current, charging a 10 nF gate capacitance from 0 V to 10 V in approximately 67 ns. In a 500 kHz buck converter, this fast transition reduces switching losses by limiting the cross-conduction interval to under 20 ns, improving converter efficiency by 1% to 3% compared to a 0.5 A gate driver.
How does TC4627EPA's high-side driver capability with boost supply work in a half-bridge MOSFET stage?
The boost pin accepts a bootstrap voltage higher than the main supply rail, allowing the driver to pull the gate of a high-side N-channel MOSFET above the switch-node voltage. For a 48 V half-bridge, the bootstrap capacitor charges to approximately 60 V (48 V plus the gate drive voltage), enabling full enhancement of the high-side MOSFET and on-resistance reduction to the specified RDS(on) value.
For a through-hole prototype power board, why is the TC4627EPA 8-pin PDIP an advantage over SOIC gate drivers?
The 8-pin PDIP (PDIP-8, 0.3-inch row spacing) plugs directly into standard breadboards and IC sockets, enabling rapid prototyping of gate-drive circuits without soldering. This reduces development cycle time by allowing MOSFET switching waveform characterization on a bench before committing to an SMD layout, particularly useful for verifying rise times under 50 ns and ringing below 10% overshoot.
How does the non-inverting output of TC4627EPA simplify gate drive logic for PWM controllers?
The non-inverting (active-high) output means a high PWM signal from the controller turns the MOSFET on, with no firmware polarity inversion required. This direct compatibility with standard PWM controllers like UC3842 or TL494 eliminates external inverter gates, reducing the gate-drive subsystem to 2 to 3 components per switch and avoiding propagation delay introduced by additional logic stages.
What is the factory lead time for TC4627EPA and how should engineers plan procurement for production builds?
TC4627EPA has a standard factory lead time of 8 weeks, so engineering teams should place production orders at least 2 months before the planned build date. For high-volume designs above 1000 units per quarter, maintaining a 4-week rolling safety stock is advisable to absorb lead-time variability without halting production lines.
