The TLVM236x5 is a 1.5A or 2.5A, 36V input synchronous step-down DC/DC power module that combines flip chip on lead (FCOL) packaging, power MOSFETs, integrated inductor and boot capacitor in a compact and easy-to-use 3.5mm × 4.5mm × 2mm, 11-pin QFN package. The small HotRod ™ QFN package technology enhances the thermal performance, ensuring high ambient temperature operation. devices can be configured for 1V up to 6V output with a resistor feedback divider.

The TLVM236x5 is specifically designed to meet low standby power requirements for always on, industrial applications. Auto mode enables frequency fold back when operating at light loads, allowing a no load current consumption of 1.5μA at 13.5V VIN and high light load efficiency. A seamless transition between PWM and PFM modes along with low MOSFET on resistances provide exceptional efficiency across the entire load range.

The TLVM236x5 uses peak current mode architecture with internal compensation to maintain stable operation with minimal output capacitance. The RT pin can be used to set the frequency between 200kHz and 2.2MHz to avoid noise sensitive frequency bands.

TLVM23615RDNR Pinout

Package: 11-PowerFQFN Module

Notes

• Pin 10 (RT/GND): Factory-set for fixed switching frequency MODE/SYNC variants only. See Device Comparison Table for RT variant details.
• Pin 11 (MODE/SYNC): Factory-trimmed and factory-set for externally adjustable switching frequency RT variants only in some configurations.
• Pins 5 & 6 (SW): Both pins are switch outputs; they may be connected together or used separately depending on application.
• Pin 4 (VOUT): Output voltage node.
• Pin 7 (BOOT): Bootstrap supply for high-side gate driver.

Limits apply over T J = -40°C to 125°C, VIN = 24 V, VOUT = 3.3 V, FSW = 1000 kHz (unless otherwise noted). Minimum and maximum limits are specified through production test or by design. Typical values represent the most likely parametric norm and are provided for reference only.

• (2) A voltage of 2 V below PGND and 2 V above VIN can appear on this pin for ≤ 200 ns with a duty cycle of ≤ 0.01%.

Limits apply over T J = -40°C to 125°C (unless otherwise noted).

The TLVM236x5 only requires a few external components to convert from a wide range of supply voltages to a fixed output voltage. To expedite and streamline the process of designing of a TLVM236x5, WEBENCH online software is available to generate complete designs, leveraging iterative design procedures and access to comprehensive component databases. The following section describes the design procedure to configure the TLVM236x5 power module.

As mentioned previously, the TLVM236x5 also integrates several optional features to meet system design requirements, including precision enable, UVLO, and PGOOD indicator. The application circuit detailed below shows TLVM236x5 configuration options suitable for several application use cases. Refer to the TLVM23625EVM User's Guide for more detail.
