The LTC7001 is a fast high side N-channel MOSFET gate driver that operates from input voltages up to 135V. It contains an internal charge pump that fully enhances an external N-channel MOSFET switch, allowing it to remain on indefinitely.
Its powerful driver can easily drive large gate capacitances with very short transition times, making it well suited for both high frequency switching applications or static switch applications that require a fast turn-on and/or turn-off time.
The LTC7001 is available in the thermally enhanced 10-lead MSOP package.
- Static Switch Driver
- Load and Supply Switch Driver
- Electronic Valve Driver
- High Frequency High Side Gate Driver

Evaluation Kits (2)
The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:
- Boost and Buck converter elements and open-loop operation
- Buck Converters: closed loop operation
- Boost Converters: closed loop operation
The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:
- 5V USB wall adapter
- Basic adjustable power supply for input power (0-12V, 2A)
- ADALM2000 or basic oscilloscope (2 channels with trigger, >10MHz bandwidth)
Features & Benefits
- Companion module for Active Learning labs on buck and boost power converters
- Illustrates important concepts related to buck and boost converters:
- Continuous vs. Discontinuous Conduction Modes
- Open loop operation
- Voltage mode control
- Current mode control
- Independently adjustable parameters: frequency, duty cycle, voltage/current mode
- Onboard current sense amplifiers and adjustable load minimize equipment requirements.
Demonstration circuit 2708A is a 135V, high side switch featuring the LTC7001. The demo board is designed to switch a 5A output load from 0V up to 135V. This board offers a low 50ns (typical) propagation delay, fast switching times (<10ns) and 100% duty cycle operation.
