Product details
Overview
EV2152-TF-00A from Monolithic Power Systems is a 2A synchronous step-down DC/DC converter IC with 25μA quiescent current, 1.1MHz fixed switching frequency, and 2.5V–5.5V input range. It delivers regulated 1.2V output using internal 75mΩ/45mΩ MOSFETs in a SOT563 package, targeting low-power portable devices requiring high light-load efficiency and fast transient response.
For engineers reviewing the EV2152-TF-00A datasheet, EV2152-TF-00A pinout, EV2152-TF-00A application, or EV2152-TF-00A equivalent, key selection criteria include ultra-low IQ for battery longevity, Constant-On-Time control for stability without external compensation, EN pin for power sequencing, 1% FB accuracy, and hiccup-mode short-circuit protection.
Technical Context
The EV2152-TF-00A implements a Constant-On-Time (COT) control architecture that enables near-instantaneous load transient response and eliminates the need for loop compensation components. Its internal power stage integrates asymmetric N-channel MOSFETs (75mΩ high-side, 45mΩ low-side) optimized for high efficiency across 0–2A output current.
It supports 100% duty-cycle operation for minimum dropout, includes output discharge, Vo overvoltage protection, and thermal shutdown. The fixed 1.2V output version features a Power Good (PG) signal, while the adjustable variant uses external resistor dividers for output setting down to 0.6V.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 2.5V–5.5V; requires local 22μF ceramic input capacitor for stability |
| GND | Power Ground | Common return path for input/output currents and IC substrate; must be low-impedance plane |
| SW | Switch Node | Connects to external inductor; carries high di/dt square wave; critical for EMI and layout |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS62864DRLR | 1.8V–5.5V input, 2A, 15μA IQ, 2.5MHz switching - higher frequency but tighter VIN min | Lacks PG pin; no hiccup-mode short-circuit recovery | Preferred where board area is constrained and 2.5MHz allows smaller inductors |
| Analog Devices LT8610ABEDD#TRPBF | 3V–42V input, 2A, 2.5μA IQ, 2MHz - wide VIN but higher cost and larger QFN-10 | Includes spread-spectrum EMI reduction; no integrated PG | Selected for automotive or industrial environments requiring extended input range and ultra-low IQ |

FAQ
What is the recommended input capacitor for EV2152-TF-00A?
A 22μF X5R ceramic capacitor rated for ≥10V is required at the VIN pin, placed as close as possible to the SOT563 package. For VIN < 3.3V, two parallel 22μF capacitors are recommended to maintain stability under high ripple current.
Does EV2152-TF-00A support adjustable output voltage?
No - EV2152-TF-00A is the fixed 1.2V output version with integrated feedback resistors and Power Good (PG) functionality. Adjustable versions use part numbers like MP2152GTF-XX or MP2152GTF without the "-00A" suffix.
How does the Power Good (PG) pin operate?
The PG pin is an open-drain output that pulls low when VOUT deviates by more than ±10% from 1.2V. It asserts high after a 1ms delay once regulation is achieved, enabling safe system power sequencing and reset generation.
Can EV2152-TF-00A operate at 100% duty cycle?
Yes - the device supports 100% duty-cycle operation, allowing VOUT to track VIN down to the dropout voltage (typically ~150mV at 2A), which is essential for maintaining regulation during battery voltage sag.
What thermal derating applies in SOT563 package?
In a standard 2-layer 1oz copper PCB with 100mm² exposed pad copper, the EV2152-TF-00A delivers full 2A output up to +65°C ambient. Above this, current must be linearly reduced to maintain junction temperature ≤125°C.
Is output discharge active during EN deactivation?
Yes - when EN is pulled low, the internal discharge FET activates and safely bleeds the output capacitor to GND within ~100μs, preventing back-powering of upstream circuitry or undefined logic states.
What is the minimum recommended output capacitance?
A minimum of 22μF X5R/X7R ceramic capacitor is required at VOUT. Lower values may cause instability or excessive output ripple due to the COT control loop's dependency on output capacitor ESR and capacitance.
