Product details

Overview

MP2330HGTL-Z from Monolithic Power Systems is a fully integrated 24V-input, 3A-output synchronous buck converter in SOT583 package, featuring 1.2MHz switching frequency, constant-on-time (COT) control, 75mΩ/40mΩ internal MOSFETs, and power-good (PG) output. It delivers tight regulation across 4.2–24V input and supports pre-bias start-up for reliable power sequencing in compact consumer electronics.

For engineers reviewing the MP2330HGTL-Z datasheet, MP2330HGTL-Z pinout, MP2330HGTL-Z application, or MP2330HGTL-Z equivalent, key selection criteria include COT-based transient response, thermal shutdown at 150°C, programmable soft-start via external capacitor, and PG open-drain signaling with 87–97% VREF rising threshold.

Technical Context

The MP2330HGTL-Z employs constant-on-time (COT) control with input- and output-voltage-dependent on-timer to maintain stable ~1.2MHz operation across wide VIN range. Its valley-current sensing enables precise over-current protection with hiccup-mode recovery.

Internal bootstrap circuitry sustains high-side gate drive using a floating 1µF BST capacitor; dead-time control prevents shoot-through between 75mΩ HS and 40mΩ LS N-channel MOSFETs. The device operates exclusively in forced continuous conduction mode (CCM) with TON extension down to 280kHz under low-VIN dropout conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	4.2V to 24V - supports wide industrial and consumer supply rails including 5V, 12V, 19V, and 24V systems
Output Current	3A continuous - delivers full rated load without derating at TA = +25°C on standard 2-layer PCB
Switching Frequency	1.2MHz typical - enables compact LC filter design with ≤2.2µH inductors and minimal footprint
Feedback Reference	805mV ±16mV - sets output voltage accuracy; used with resistor divider to configure 0.8V–13V outputs
Quiescent Current	200µA typical - minimizes no-load power loss in always-on subsystems like standby logic rails
Thermal Shutdown	150°C junction - protects against sustained overload; hysteresis of 20°C ensures stable re-enable at 130°C
Power Good Threshold	Rising: 92% VREF, Falling: 87% VREF - provides clean system enable/disable signaling with 50µs delay

Pinout & Package

SOT583 (1.6mm × 2.1mm) thermally enhanced 8-pin package with exposed thermal pad; pin 1 marked by dot, top-view orientation as per MPS datasheet Rev. 1.0.

Pin/Terminal	Circuit Role	Design Meaning
1 - PG	Open-drain power-good indicator	Pulled low during startup/fault; requires external pull-up; asserts high only after SS completion and VOUT within 87–120% VREF
2 - IN	Main input supply rail	Accepts 4.2–24V; must be decoupled with ≥22µF ceramic capacitor placed adjacent to pin; wide trace required
3 - SW	Switch node	Connects to inductor; carries high di/dt; requires short, low-inductance routing and Kelvin connection to GND
4 - GND	System ground reference	Primary return path for power and feedback; must be tied to thermal pad and connected via multiple vias to inner ground plane
5 - BST	Bootstrap supply for high-side driver	Requires 1µF X7R ceramic capacitor between BST and SW; enables floating gate drive for HS-FET
6 - EN	Enable control input	Logic-high (>1.23V) enables regulator; internal 2.8V Zener clamp limits voltage; 604kΩ pull-up to VIN enables auto-start
7 - SS	Soft-start timing node	Charged by 7.3µA internal current source; external capacitor sets ramp time per C_SS = (T_SS × 1000) / (2 × 0.805)
8 - FB	Feedback input	Monitors output via resistor divider; 10–80nA bias current enables high-impedance networks for low quiescent loss

Key Features

Feature	Design Value
Constant-on-time (COT) control	Delivers <100µs load transient response without external compensation components
Pre-bias start-up capability	Enables monotonic ramp-up into already-biased outputs-critical for multi-rail SoC power sequencing
Programmable soft-start	External capacitor sets ramp duration from 1ms to >100ms, preventing inrush into large output capacitors
Integrated 75mΩ/40mΩ MOSFETs	Eliminates external power switches and reduces BOM count while maintaining >90% efficiency at 3A/3.3V
Hiccup-mode OCP	Auto-retries after fault clearance-avoids latch-off in intermittent overload scenarios like hot-plug events

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous buck converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP2330GTL-Z	Same die, SOT563 package (1.6mm × 1.6mm); higher θJA (130°C/W), lower max output current (2.5A)	Limited to lower-power applications due to reduced thermal performance; not suitable for sustained 3A loads	Select MP2330HGTL-Z when full 3A continuous output and superior thermal resistance (55°C/W θJA) are required.
TPS543320RTWR	4.5–18V input, 3A, 2.2MHz, PMBus-enabled; requires external compensation and has larger QFN package	Supports digital configuration and telemetry but adds firmware overhead and layout complexity	Choose MP2330HGTL-Z for analog simplicity, smaller footprint, and cost-sensitive designs lacking PMBus infrastructure.

FAQ

What is the minimum recommended output capacitor value for stable operation at 3.3V/3A?

The MP2330HGTL-Z requires ≥44µF total output capacitance for stable 3.3V operation at full load, as validated in the typical application circuit. Ceramic or POSCAP types are recommended; ESR must be ≤10mΩ to limit ripple-induced regulation error. Lower values risk instability under heavy transient loads.

Does the MP2330HGTL-Z support forced PWM mode across all load conditions?

Yes-the MP2330HGTL-Z operates exclusively in forced continuous conduction mode (CCM) regardless of load current. Unlike auto-mode buck converters, it does not enter discontinuous conduction mode (DCM) or pulse-skipping, ensuring consistent 1.2MHz switching and predictable EMI profile even at light loads.

How is the soft-start time calculated for a given external capacitor value?

Soft-start time (T_SS) in milliseconds is calculated as T_SS = (2 × V_REF × C_SS) / I_SS, where V_REF = 0.805V, I_SS = 7.3µA typical, and C_SS is in nanofarads. For example, a 100nF capacitor yields ~22ms ramp time. This relationship is confirmed in the datasheet's Equation (1).

Can the MP2330HGTL-Z safely start into a pre-biased output voltage?

Yes-it features dedicated pre-bias start-up circuitry that monitors FB voltage during enable and refreshes the BST capacitor before initiating switching. This ensures monotonic output ramp without reverse current flow, making it suitable for hot-swap and multi-rail sequencing applications.

What is the maximum allowable input voltage for continuous operation?

The absolute maximum input voltage is 26V, but continuous operation is specified up to 24V per Recommended Operating Conditions. Operation above 24V risks exceeding internal UVLO hysteresis margins and may trigger premature shutdown; sustained 26V violates reliability stress limits and is not qualified.

Is an external bootstrap diode required for the BST pin?

No-bootstrap charging is fully integrated. The MP2330HGTL-Z includes an internal charge pump and regulation circuit that maintains BST voltage using only an external 1µF ceramic capacitor between BST and SW pins. Adding an external diode degrades performance and is explicitly discouraged in the datasheet.

How does the power-good (PG) signal behave during thermal shutdown?

During thermal shutdown, the PG pin is actively pulled low within 35µs of junction temperature exceeding 150°C. It remains low until both temperature falls below 130°C *and* output voltage recovers to within 87–120% of VREF *and* soft-start completes-ensuring system-level fault isolation and safe restart coordination.
