Description

General part information

MAX15157D Series

The MAX15157D is the evolution of the MAX15157B HV buck controller family. The MAX15157D implements a single-phase, PWM valley current-mode controller and drives two external power MOSFETs in a buck configuration. The output voltage can be dynamically set through the 1V to 2.2V reference input (REFIN) for modular design support.The switching frequency is controlled either through external resistor that sets the internal oscillator, or by synchronizing the regulator to an external clock. The device is designed to support 60kHz to 1MHz switching frequencies. The controller has a dedicated undervoltage lockout pin (UVLO) and an accurate enable input threshold for flexible power sequence configuration. The controller also has multiple fault-protection circuits to protect against overcurrent (OCP) adjustable through the ILIM pin, output overvoltage (OVP), input undervoltage (UVLO), and thermal shutdown.The MAX15157D features an adjustable internal compensation ramp. The device incorporates an accurate current-sense amplifier that reports output current through an analog output (IMON).The MAX15157D features lossless LS FET RDSONor resistor current sensing. The device allows programmable single-phase or multiphase operation, up to eight interleaved phases, and implements an accurate current balance scheme. The MAX15157D can operate with either discrete inductors or coupled inductors in case of multiphase operation.The device is available in a 5mm × 5mm, 32-pin TQFN package and supports a -40°C to +125°C junction temperature range.ApplicationsData CenterIndustrialMultiphase Buck
