Analog Devices Inc./Maxim Integrated MAX17075EVKIT+

Overview

MAX17075EVKIT+ from Analog Devices is an evaluation kit for the MAX17075 TFT LCD power management IC - a highly integrated solution featuring a 1.2MHz current-mode boost regulator (up to 18V), dual regulated charge pumps (±30V/–7V), high-current VCOM op amp (±500mA, 45V/µs), and gate-driver timing switches. It supports notebook displays, LCD monitors, and LCD TVs requiring compact, ultra-thin panel power architectures.

For engineers reviewing the MAX17075EVKIT+ datasheet, MAX17075EVKIT+ pinout, MAX17075EVKIT+ application, or MAX17075EVKIT+ equivalent, this kit enables rapid validation of the MAX17075's full power tree - including AVDD (13V/500mA), VGON (+30V/20mA), VGOFF (–7V/20mA), and VCOM drive - under real pulsed-load conditions typical of TFT source/gate drivers.

Technical Context

The MAX17075EVKIT+ implements the complete reference design from the MAX17075 datasheet (Figure 1), delivering three independent, regulated outputs: a 13V/500mA source driver supply (AVDD) via the integrated 1.2MHz boost regulator; a +30V/20mA positive gate-on supply (VGON) via the regulated positive charge pump; and a –7V/20mA negative gate-off supply (VGOFF) via the regulated negative charge pump. All outputs feature digital soft-start, fault latching, and adjustable feedback dividers.

It validates the MAX17075's high-current VCOM buffer (rail-to-rail output, 20MHz bandwidth, ±500mA short-circuit current) driving LCD backplane loads, alongside logic-controlled high-voltage switches (SRC/DRN/COM) with programmable delay (DEL pin) for precise gate timing sequencing in TFT panels.

FAQ

What does the MAX17075EVKIT+ evaluate?

The MAX17075EVKIT+ evaluates the MAX17075 IC - a complete TFT LCD power management device integrating a 1.2MHz boost regulator (up to 18V), dual regulated charge pumps (VGON/VGOFF), a ±500mA VCOM op amp, and gate-driver timing switches. It implements the Figure 1 reference circuit from the MAX17075 datasheet with all critical passive components pre-installed and optimized.

Does the MAX17075EVKIT+ support adjustable output voltages?

Yes - the MAX17075EVKIT+ supports full adjustment of all regulated outputs via external resistor dividers: AVDD (via FB pin), VGON (via FBP pin), and VGOFF (via FBN pin). The kit includes populated resistors matching the typical 13V/30V/–7V configuration but allows reconfiguration for other target voltages within the MAX17075's specified ranges.

Can the MAX17075EVKIT+ validate the VCOM amplifier's performance?

Yes - the MAX17075EVKIT+ provides direct access to the POS, NEG, and OUT pins of the MAX17075's integrated VCOM op amp, enabling measurement of its rail-to-rail output swing, ±500mA short-circuit current, 45V/µs slew rate, and 20MHz bandwidth under load. Test points and bypass capacitors are placed per layout best practices in the MAX17075 datasheet.

How is gate-driver timing controlled on the MAX17075EVKIT+?

The MAX17075EVKIT+ implements the MAX17075's gate-driver timing block using the CTL, DEL, SRC, DRN, and COM pins. A capacitor on the DEL pin sets the programmable delay between gate-on and gate-off switching events. The kit routes CTL to a header for external logic control and exposes SRC/DRN/COM for oscilloscope probing of high-voltage switching waveforms.

What input voltage range does the MAX17075EVKIT+ accept?

The MAX17075EVKIT+ accepts a single 2.5V to 5.5V DC input (e.g., 3.3V or 5V system rail) applied to the VIN terminal. This powers the MAX17075's VCC and PGND rails, enabling the full power tree - AVDD, VGON, VGOFF, and VCOM - to operate as specified in the MAX17075 datasheet across its full temperature range.
